Crash on 'info locals' #3

Closed overloader7 closed 1 year ago

overloader7 commented 1 year ago

I don't know where i should put this, but gdb crashes on 'info locals' when trying to read bad(null and nearby) char pointers in the latest release. The previous release works fine. Using Windows 7, so that might have something to do with newer versions of python not being supported on it (although everything else seems to work fine).

I also test on Windows 7, so that shouldn't be the problem. Can you maybe create a small reproducer for me, because I don't think that I've had this problem.

You may also want to try the upcoming gdb-13 version, maybe this was already fixed. I've put a test build here (compressed twice, because for some reason github doesn't like 7z files): gdb64-python_2.zip

This gdb-13 build indeed works fine, so it was probably fixed.

But just in case it matters, just a declared WNDCLASSEX variable from windows.h, compiled with -m64 -ggdb3 -O0, gcc version 12.2.0 (x86-64-win32-seh-rev2) in gdb 12.1.90.20220502-git, commands start, info locals, it writes things up to hbrBackground (after it should come a const char* value) and crashes.
