Hi Jason,

In its most simple expressioj, just load the program in GDB:

  $ gdb <program>

and run it:

  (gdb) run

If the program crashes (receives a SIGSEGV / segmentation fault signal),
it will stop and you'll be able to inspect the state of the program at
that moment.  For example, you'll be able to use the "backtrace" command
to get an idea of wherwe the program was.

Simon
