Line number of segmentation fault

Question

Is there any gcc option I can set that will give me the line number of the segmentation fault?

I know I can:

1. Debug line by line
2. Put printfs in

Answer 1

Here's a complete shell/gdb session

$ gcc -ggdb myproj.c
$ gdb a.out
gdb> run --some-option=foo --other-option=bar
(gdb will say your program hit a segfault)
gdb> bt
(gdb prints a stack trace)
gdb> q
[are you sure, your program is still running]? y
$ emacs myproj.c # heh, I know what the error is now...

Happy hacking :-)
