igartner:
I have a simple program, compiled with -g for debugging, put a break point and try to debug.
The program stops at the indicated location for one sec and then disappears Gdb returning 1: here is the debug log

Please help, thanks igartner

oBFusCATed:
The gdb we're shipping as part of the installer and the mingw-w64 version we've selected turned out to be problematic. You have to find a version which works better. :(

igartner:
Excuse m, but if I understand you well, your advice is to install an older version, correct?

I think his advise is to install a different Compiler/Debugger; but, that is just a guess on my part.

oBFusCATed:
Different version of the debugger which is compatible with your compiler (32 compiler should have 32 bit debugger, and vice versa for 64 bits). I'm not a windows user, so I cannot give advice about which versions work and which doesn't.
