enable the full debug log in Settings->Debugger->Common
then post the debug log, found in the debug log tab in the logger pane here in code tags (# symbol in the forum editor)

Probably you have a broken gdb...

well, so far I discovered this feature is breaking the debugging process
here is the full log. I put a bp - debugger stoped - I opened asm view - debbugger terminated after a second or so

Yes, gdb 8.3 shipped with codeblocks is broken... You probably need a newer version of gdb,
for example:

uh...so i have to download gcc and mingw and extract both in the folder where the current gdb.exe is located?!?!?


edit:
downloaded win64 version without LLVM/Clang/LLD/LLDB and extracted it into CodeBlocks\MinGW and replaced any conflicting file. hope I've done correctly


edit 2 :
YOU ARE AWESOME. fixed man. works like a charm.thx for the uber support

anyway, shouldn't the 20.3 package be updated?!
