Question

I have some code, that I’m currently porting from OS X to Linux (console tool).

Somewhere in this code, I get a segmentation fault. The problem is, that if I run the program without GDB, I clearly see the segmentation fault, and the program is killed. But when I’m running GDB it just halts, and GDB never returns to the prompt. So I’m not really able to examine what’s going on.

C++ is the code. Compiled with the -g option in g++.

Btw. Pretty new to GDB, so excuse me if this is obvious.

Any ideas?
Thanks in advance.

The behaviour you describe is not typical – I suspect the stack may have been trashed.

Try sending various signals directly via the ‘kill’ command.

Might be worth you running a test program in gdb with an abort() in it so that you can learn what the expected behaviour is for gdb.
