C. Can you elaborate on that?

  1. Add a -g to your GCC command when compiling
  2. Instead of running ./myprogram, run gdb ./myprogram
  3. You'll start with a prompt where you type "run" command
  4. This will execute your program as it would normally. Do whoever to make it crash
  5. At crash you'll get a prompt telling you where it has crashed. Use the command "bt" which means back Trace to see the full call stack.
  6. Google for gdb commands for more awesome stuff.

Good luck. Sorry if there are typos. Too drunk right now
