I'm a beginner and need help about "Segmentation fault" error.

And when the -g is enabled, do not strip the symbols from the binary. So remove '-s' if you have in the compilation process, and remove 'strip' commands which might be triggered on the compiled object files after they were compiled.

without optimization (-O0).

I also suggest you search and read for any GDB tutorial out there, it
will walk you though these steps.
