If you can't set a break point for some reason, you can call this
function where you want gdb to break:

void
stop_in_debugger(void)
{
  void (* saved_handler) (int);

  saved_handler = signal (SIGINT, SIG_IGN);
  raise (SIGINT);
  signal (SIGINT, saved_handler);
}

I originally found this routine while browsing through the Nautilus
source code, and it comes in handy from time to time.
