I'm trying to build a node module on Windows 10 with MS VS 2015 and for some reason it's unable to resolve library symbols on node-gyp build. Here is my binding.gyp file:
{
'variables' : {
'include_path' : 'path/to/include',
'lib_path': '/path/to/lib',
},
'targets': [
{
// name and sources here
'include_dirs': [
'<(include_path)',
],
'libraries': [
'<(lib_path)',
],
},
],
}
For some reason, it's unable to resolve any symbols in the library. Here is a snippet of the output:
ProjectBuild.obj : error LNK2001: unresolved external symbol __imp__AiMsgSetLogFileFlags [\path\to\build\project_build.vcxproj]
ProjectBuild.obj : error LNK2001: unresolved external symbol __imp__AiRenderInterrupt [\path\to\build\project_build.vcxproj]
In addition, here is the disassembly of those symbols in the object file dump for that library:
Disassembly of section .text:
0000000000000000 <AiMsgSetLogFileFlags>:
0: ff 25 00 00 00 00 jmpq *0x0(%rip) # 6 <AiMsgSetLogFileFlags+0x6>
6: 90 nop
7: 90 nop
ai.dll: file format pei-x86-64
Disassembly of section .text:
0000000000000000 <AiRenderInterrupt>:
0: ff 25 00 00 00 00 jmpq *0x0(%rip) # 6 <AiRenderInterrupt+0x6>
6: 90 nop
7: 90 nop
ai.dll: file format pei-x86-64
I can confirm with 100% certainty that node-gyp is finding the library file. Does anyone know why it's having trouble linking the symbols in that file? For what it's worth, I'm able to build the module just fine in a linux environment with the exact same binding.gyp file.
You need to look into making sure that the symbols you want to export have this. https://msdn.microsoft.com/en-us/library/3y1sfaz2%28v=vs.140%29.aspx

I'm new to using windbg. I'm trying to determine root cause of why an application throws abnormal program termination. It's a updater app that downloads password protected zip files and unpacks them to make an update.
Typically, these errors are caused a network device blocking the download. But I want to know for sure if its the download or the unzip causing this. I created a dump file using Windows Task Manager when the error was shown on the screen.
I've gotten as far as the output below in windbg. I'm not sure where to go from here. I think the error happened on thread 2 because it has Unhandled Exception Filter. I tried dumping out the dwords for the return addresses but I'm not sure what that output means; just a bunch of bytes to me.
Any advice on how to continue investigating this would be appreciated.

I have created a minimal reproduction of an issue I am having, trying to create a C++ based Python3 module. The build environment is CMake, Visual Studio Pro 2019, WinSDK 10.0.18362, Python 3.9.4. When executing:
python3 -c "import pymod"
I will get an exception in release mode with a NULL access. In debug Python, I get additional information.
My CMakeLists.txt
cmake_minimum_required(VERSION 3.15)
project(pymod_minimal_repo_example)
find_package(Python3 COMPONENTS Interpreter Development)
add_library(pymod SHARED)
target_sources(pymod PRIVATE pymodmodule.cpp)
set_target_properties(pymod PROPERTIES SUFFIX ".pyd")
target_compile_options(pymod PRIVATE /Zi)
target_link_options(pymod PRIVATE /DEBUG:FULL)
target_link_libraries(pymod PRIVATE ${Python3_LIBRARIES})
target_include_directories(pymod PRIVATE ${Python3_INCLUDE_DIRS})
Following this python reference: https://docs.python.org/3.9/extending/extending.html#a-simple-example I created the following:
#define PY_SSIZE_T_CLEAN
#include <Python.h>
static struct PyModuleDef pymodmodule = {
PyModuleDef_HEAD_INIT, // m_base
"pymod", // m_name
NULL, // m_doc
-1, // m_size - submod not support must be static struct
NULL, // m_methods - no functions present
NULL, // m_slots - must be NULL
NULL, // m_traverse - not needed
NULL, // m_clear - not needed
NULL // m_free - not needed
};
PyMODINIT_FUNC PyInit_pymod(void) {
return PyModule_Create(&pymodmodule);
}
It is a functionally void module which does nothing, but should still run. Note that having m_methods defined, produces the same failure.
When the failure occurs, the following is output to the console:
E:\projects\pymod\build\Debug>python -c "import pymod"
Fatal Python error: _PyInterpreterState_GET: the function must be called with the GIL held, but the GIL is released (the current Python thread state is NULL)
Python runtime state: unknown
WinDbg jit debugger then catches the issue. A partial call stack shows my PyInit_pymod is called and when creating the python module, it cascades to a failure:

I cannot find any information on the console message, nor the int3. I have tried full purge and reinstall/update of Python.
Can anyone offer some direction to help, or know the cause?
Edit: Modified that PyModule_pymod function to display Pre and Post msg to console. Debug build exceptions, Release appears not to:
PyMODINIT_FUNC PyInit_pymod(void) {
printf("Pre-PyModule_Create\n");
PyObject *obj = PyModule_Create(&pymodmodule);
printf("Post-PyModule_Create\n");
return obj;
}

Fatal Python error: _PyInterpreterState_GET: the function must be called with the GIL held, but the GIL is released (the current Python thread state is NULL)
Python runtime state: unknown
I ran into the same issue as you, and while debugging TLS structures, I noticed that Visual Studio had loaded python310.dll instead of python310_d.dll.
To make a long story short, when you define the _DEBUG macro, Python.h will use python310_d.lib, so you need to run the debug version of Python:
python_d -c "import pymod"
I was confused further by the fact that I did not have this issue while using pybind11. As it turned out, pybind11 undefines the _DEBUG macro while including Python.h, so it is always using python310.lib instead of python310_d.lib, even for debugging builds.
As I do not see an option to use the python_d interpreter in Visual Studio, I ended up using the release library for debugging builds using the following code:
#if defined(_MSC_VER) && defined(_DEBUG)
#undef _DEBUG
#include <Python.h>
#define _DEBUG 1
#else
#include <Python.h>
#endif
As a sidenote, when you link against python310_d.dll, you will have to name your debug module pymod_d.pyd instead of pymod.pyd.
I got an c0000005 memory exception when my program use a newer version of c++ runtime, specifically of msvcp140.dll :

It seems it had a different std::exception_ptr, changing version from 14.16.27012.6 to 14.24.28127.4 of msvcp140.dll.
I assumed compatibility was maintained in this case when only the build / minor version changes.

If I run it on my primary system (on which I compiled the program), and then load the .dmp-file in Visual Studio or WinDbg, the full stack trace is displayed correctly and I can see where the error has occurred:

There are no warnings or errors from what I can tell, so why am I not getting the full stack trace information?
VCRUNTIME140!_CxxThrowException+0xad [f:\dd\vctools\crt\vcruntime\src\eh\throw.cpp # 133]
versus
VCRUNTIME140!_CxxThrowException+0xc2 [f:\dd\vctools\crt\vcruntime\src\eh\throw.cpp # 136]
is a bit worrying. It suggests that the minor version of the MSVC runtime doesn't match between the two machines (because otherwise, why would they invoke RaiseException from different source lines). If your WinDbg session doesn't have symbols for the remote machine's VCRUNTIME140 -- or, worse yet, if it's using the wrong PDB for it -- backtracing is going to become problematic at that point. WinDbg should automatically download and load symbols for whichever version is referenced from the minidump, but I suspect this isn't happening properly.
Use lm v to show the module listing for the minidump, and pay close attention to the checksum information. I suspect you'll see a different checksum for vcruntime140.dll between the two machines. If you do, you'll need to figure out why you're not getting the right symbols for the dll.
Thanks to the tips by users Sneftel and Sean Cline, I found the solution. Running the command !itoldyouso vcruntime140 gives me the following output:
sig MISMATCH: vcruntime140.amd64.pdb and VCRUNTIME140.dll
The problem was that my system which I use for debugging runs on an AMD CPU, while the system that generated the crashdump runs on an intel CPU. For some reason the vcruntime140.dll is system-specific and differs between the two. (Also, on AMD systems the pdb is called "vcruntime140.amd64.pdb", on intel it's "vcruntime140.i386.pdb".)
I've copied the vcruntime140.dll, vcruntime140.i386.pdb and msvcp140.dll from my intel system and added them to the symbol path for WinDbg. Then I ran the same commands as before, and now it outputs the full stacktrace.

Recently we are seeing a significant increase in crashes related to COM at our client sites after they upgraded to Windows Server 2008R2. Initially we thought it might be due to COM reference counting issue, but after further investigation going through the code, we have ruled it out. Another angle that we are looking at is, is it possible that the COM library is getting un-initialized due to which this issue might be occurring? Again we have ruled it out after investigating going through the code. As of now we do not have any concrete answers.
Is there any known instances of COM crashes increasing after migrating to 64bit?
Below are the crash fingerprints. I have kept it concise for this post.
