How to view an assembly code while debugging?
visir:
I'm paused at the first line of main(), and opened Debug -> Debugging windows -> Disassembly, but it's empty.
When on windows, and when using mingw and gdb, is it possible to see the resulted assembly code? Or should I generate assembly listings?
visir:
Actually, even keeping the disassembly window open breaks the debugger. It like halts, I can't even stop the debugging without closing gdb.exe in the task manager. Stepping doesn't work too.
visir:
This is what it prints in log when I open assembly window
[debug]> if 1
disassemble 0x4016b5
info frame
end

After that, it stops reacting to anything.
BlueHazzard:
have you enabled full debugger log?
Settings->Debugger->Common->Full (Debug) log ?
try again, and post the full debug log
for me the disassembly works. What codeblocks version are you using?
visir:
full debugger log enabled.
codeblocks version is 16.01 , "Build: Jan 25 2016, 21:19:34 - wx2.8.12 (Windows, unicode) - 32 bit". Should be the last, I downloaded it half a month or month ago.
It's 32bit codeblocks with 32bit compiler and debugger on 64bit windows, hope that's not a problem.
Here is the full log.
