### python3.11 configure.ac
only add "-gdwarf-4" to OPT , because my gdb does not support dwarf5

I Compile Python3.11 without any changes, but GDB does not support DWARF5, so I added "-gdwarf-4" to build. Then I use gdb, gdb gets stuck。 I want use gdb to debug my program 。 I have tried build python2.7 with '-gdwarf-4' ,and the result is same。
Before command 'make install' , gdb is not stuck when I use command 'gdb python3.11'

It is a known bug for this version of GDB. This link may help you.
When I changed my cygwin to 64 version, the problem is suprisely solved.
I think this may be another a bug which differ from the "well-known" GDB bug.
I want to debug my application written in C++ in Eclipse via network. I followed this tutorial http://janaxelson.com/eclipse5.htm but when debugging starts it gives me strange segmentation fault. Full log:

I can't figure out what's wrong.
My setup is
Ubuntu 15.04, gcc version 4.9.2, gdb 7.9, Eclipse Mars
Target machine:
Ubuntu 14.04.2 LTS, gdb 7.7.1, gdbserver 7.7.1
I've been installed Cygwin for windows x64.
After installation, I noticed that the system can find everything.
In the console:

Then, when I create a project in eclipse, I get this error message when you try to compile it:
How can I fix it?
Thanks!
You must setup your compiler location.
You can do this in Project->Properties->C/C++ Build -> Settings -> Toolchains Tab.
For example, I use compiler from CodeSourcery Lite version.
So, I choose "C:\Program Files (x86)\CodeSourcery\Sourcery_CodeBench_Lite_for_ARM_EABI\arm-none-eabi" in Global path field.
See image: https://yadi.sk/i/Zx_KkMs5X7TKg
In addition, You have some trouble in Node.cpp file...
But I need to see this file to say what's wrong...
Good Luck!

We have upgraded our C compiler to 4.5.3 and are now experiencing problems when trying to debug the server binary on solaris (works fine on linux rhel5 and AIX 6.1)
Below is the log of a debugging attempt. Any help would be appreciated.

I have just used macports to install on my Mac the newest gdb by using sudo port install gdb. The problem is when I type gdb in the command line it still shows the old version. How can I switch to the new one I just installed?
Thanks.
Type :
port contents gdb
It gives you where is located the port
/opt/local/bin/ggdb
/opt/local/include/ansidecl.h
/opt/local/include/bfd.h
/opt/local/include/bfdlink.h
/opt/local/include/dis-asm.h
/opt/local/include/gdb/jit-reader.h

/opt/local/lib/libbfd.a
/opt/local/lib/libbfd.la
/opt/local/lib/libopcodes.a
/opt/local/lib/libopcodes.la
...
As you can see below it is named ggdb, not gdb when you have installed it with MacPorts
