That flag turns off -fomit-frame-pointer which is enabled of you have
optimization turned on:
http://gcc.gnu.org/onlinedocs/gcc-4.1.1/gcc/Optimize-Options.html

Are you compiling your code with -o in general? What happens if you
simply turn off optimization (without doing anything with
-fno-omit-frame-pointer)?
