CB 20.03 for windows, debug problems

<< < (2/2)

i386:
I download the 64bit version 'gdb-10.1.90.20201024-x86_64.7z', and extract to codeblocks installation directory. Setup the debugger as the link says.
Then setup a breakpiont and run Debugging...

Starting debugger: C:\Program Files\CodeBlocks\gdb-10.1.90.20201024-x86_64\bin\gdb.exe -nx -fullname -quiet  -args D:/devel/cb/vulkan/bin/Debug/vulkan.exe
done

Debugger name and version: GNU gdb (ssbssa-1) 10.1.90.20201024-git
Child process PID: 9436
[Inferior 1 (process 9436) exited normally]
Debugger finished with status 0

----------->
The breakpoint was skipped, and the application 'vulkan' run to the end normally[judging from 'vulkan' app log]. The break point has no effect. I am sure the breakpoint is a VALID point. why?

oBFusCATed:
Post the full rebuild and debug logs.

i386:
I uninstall th CB 20.03. Then re-install it and setup the new gdb as above. After that I find all the debug process is OK.

These are the debug boot up log, the debugger stops at the breakpoint as expected:

The uninstall/install cycle doesn't change anything in your settings.
You still don't have a clue where the problem was...
Just a note.

AndrewCot:
@i386 I have just downloaded the https://github.com/ssbssa/gdb/releases/download/gdb-10.2.90.20210425/gdb-10.2.90.20210425-i686.7z file and copied the files over the MING32 installation files.
I was able to set a breakpoint and it stooped on the breakpoint.

I suggest trying the later GDB.
