I'm getting a C1001 error while attempting to build in Visual Studio 2019 Version 16.7.2. This is a C++ project that has previously built fine until a change set I am attempting to build today.
The exact error is as follows: (with project specific path redacted)
1>d:\work\[...](82): fatal error C1001: An internal error has occurred in the compiler.
1>(compiler file 'd:\agent\_work\3\s\src\vctools\compiler\utc\src\p2\main.c', line 187)
Notes below:
The error only happens in Release. Debug builds and runs.
If I turn off all optimizations in Release the error goes away.
The location where the error occurs seems to be unrelated to recent changes I have made to the project i.e. VS is reporting the error in a translation unit that had been building without problem until unrelated changes in another TU were made.
The location where the error occurs seems to not actually be problematic in the sense that if I comment out the implementation of the function there and just return a default value from the function so that the program is syntactically correct, the error occurs in the next the function in the same file.
Turning off Whole Program Optimization and Link Time Code Generation does not fix the problem.

Hi Roger,
Thanks for reporting the bug, and including an excellently
self-contained repro, so quickly. I've investigated and this seems to
be the same issue as
https://developercommunity.visualstudio.com/content/problem/209359/ice-with-fpfast-in-156-and-msvc-daily-1413263051-p.html.
I'm closing this as a duplicate just so that people can collect
context and work-around advice in the same location, and when the
other bug is marked fixed, you can assume that this one is too.
Thanks again,

If I change settings to preprocessor file (Yes) i am not getting any error.
About my environment: Upgrading Microsoft Visual Studio 2005 to 2010
Please help.
I have had this problem with VS2015 while building locally in Windows.
In order to solve it, I deleted my build folder (Output Directory as seen in Properties/General) and rebuilt the project.
This always seems to help when strange things happen during the build.
I’ve encountered this error many times in VC++. Do the following steps. They’ve sometimes helped me with this issue:
Take a look at the exact location, pointed out by compiler error.
Find any external types or classes used there at that location.
Change the order of “include path” of those files found in step 2 and rebuild the solution.
I hope that help !!!!
I am getting same error with VC2012. Setting up the project properties Optimization to Disabled (/Od) resolved the issue.
In my solution, i've removed output dll file of the project, and I've made project rebuild.
I encountered the same error and spent quite a bit of time hunting for the problem. Finally I discovered that function that the error was pointing to had an infinite while loop. Fixed that and the error went away.
In my case was the use of a static lambda function with a QStringList argument. If I commented the regions where the QStringList was used the file compiled, otherwise the compiler reported the C1001 error. Changing the lambda function to non-static solved the problem (obviously other options could have been to use a global function within an anonymous namespace or a static private method of the class).
I got this error using boost library with VS2017. Cleaning the solution and rebuilding it, solved the problem.
I also had this problem while upgrading from VS2008 to VS2010.
To fix, I have to install a VS2008 patch (KB976656).
Maybe there is a similar patch for VS2005 ?
I got the same error, but with a different file referenced in the error message, on a VS 2015 / x64 / Win7 build. In my case the file was main.cpp. Fixing it for me was as easy as doing a rebuild all (and finding something else to do while the million plus lines of code got processed).
Update: it turns out the root cause is my hard drive is failing. After other symptoms prompted me to run chkdsk, I discovered that most of the bad sectors that were replaced were in .obj, .pdb, and other compiler-generated files.
I got this one with code during refactoring with a lack of care (and with templates, it case that was what made an ICE rather than a normal compile time error)
Simplified code:
void myFunction() {
using std::is_same_v;
for (auto i ...) {
myOtherFunction(..., i);
}
}
void myOtherFunction(..., size_t idx) {
// no statement using std::is_same_v;
if constexpr (is_same_v<T, char>) {
...
}
}
I had this error when I was compiling to a x64 target.
Changing to x86 let me compile the program.
Sometimes helps reordering the code. I had once this error in Visual Studio 2013 and this was only solved by reordering the members of the class (I had an enum member, few strings members and some more enum members of the same enum class. It only compiled after I've put the enum members first).
In my case, this was causing the problem:
std::count_if(data.cbegin(), data.cend(), [](const auto& el) { return el.t == t; });
Changing auto to the explicit type fixed the problem.
Had similar problem with Visual Studio 2017 after switching to C++17:
boost/mpl/aux_/preprocessed/plain/full_lambda.hpp(203): fatal error C1001: An internal error has occurred in the compiler.
1>(compiler file 'msc1.cpp', line 1518)
1> To work around this problem, try simplifying or changing the program near the locations listed above.
Solved by using Visual Studio 2019.
I first encountered this problem when i was trying to allocate memory to a char* using new char['size']{'text'}, but removing the braces and the text between them solved my problem (just new char['size'];)
Another fix on Windows 10 if you have WSL installed is to disable LxssManager service and reboot the PC.
I'm having trouble building a project in XE5. I made some basic changes that would in no way cause an issue, but the project fails to build. I have verified that these changes build fine on another machine, and that the projects continues to build on my machine if I undo these changes.
I have managed to narrow the cause down to the code trying to use a member variable, but it's clear this is not the actual reason for the link failure.
I have tried clearing temp files as this seems to have worked for a similar issue:
C++ Builder XE7 LME288 Error
but this does not fix the problem. For reference, i am receiving the following:
[ilink32 Warning] Warning: unknown heap name : 0x08000000 / 0x08000000
[ilink32 Warning] Warning: Error detected (LME1641)
[ilink32 Error] Error: Unable to perform link
I'm being driven crazy by this, does anyone have any ideas?
Managed to figure this out eventually, the .cbproj file had been tainted from a recent merge.
The issue was extremely sporadic, as some branches with the same project file were building, and some were not. If you're having this issue check that your project file contains the appropriate information!
I'm working on my coin at the moment, following the guide posted here:
http://devtome.com/doku.php?id=scrypt_altcoin_cloning_guide
I've used the same libraries, installed them correctly -- everything! However, I get the following error during compilation.
Commands used are:

mingw32-make: *** [build/bitcoin.o] Error 1
After reading on bitcoin forums, I found a post by shakezula that mentioned this was frequently a result of missing "__NO_SYSTEM_INCLUDES". However, that is included in my .pro file, which you can find here:

Thanks for your help.
I managed to fix this by downloading the CoinLab build environment; for those interested, the QT version was 4.8.4, with MinGW as the version bundled with GCC 4.6.2.
I'm right where you are when you posted this atm. Kinda stuck here as well... Are you using Qt 5.2? I think we may need to use 4.8.5 to get anything done.
I have the following trivial file named Temp.cpp:
#include <string>
int main() { return 0; }
and I'm trying to compile it with the following command-line in the Windows XP Free Build Environment, using WDK 7.1:
cl.exe /Iinc\api\crt\stl70 /Iinc\crt C:\Temp.cpp
and I'm getting really random errors like:
Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 15.00.30729.207 for 80x86
C:\WinDDK\7600.16385.1\inc\api\crt\stl70\iosfwd(202) :
error C2144: syntax error : 'int' should be preceded by ';'
The error goes away if I use stl60 instead of stl70, but that doesn't solve the problem.
What's the cause of the problem?
Update: I tried uninstalling and installing the WDK again, but nothing changed. :(
Update 2: Okay, apparently the error is screaming out at the header file itself: _SCL_INSECURE_DEPRECATE is the cause. Does anybody know how to turn it off correctly? (If I just comment out the lines, I get a ton more errors regarding a bunch of other macros.)
Found the answer myself, through modifying the headers and guess'n'checking:
I need to have _STL70_ defined.
Which cl.exe are you picking up? If your path happens to have an older (VC6) compiler before the WDK one, you'd expect these errors. VC6 can't compile the STL as shipped with VC7
apparently the error is screaming out at the header file itself: _SCL_INSECURE_DEPRECATE is the cause. Does anybody know how to turn it off correctly?
If you're having problems with _SCL_INSECURE_DEPRECATE, try setting:
/D_SCL_SECURE_NO_DEPRECATE
But given the error message you're seeing it sounds like you're the compiling headers with a a compiler that's older than the headers support (so this might not get you very far anyway).
