That's an interesting idea :).  Let me see, I think I would try
something like

void dump_core(void) {
  pid_t childpid;

  childpid = fork();
  switch (childpid) {
    case -1:
      /* complain fiercely: couldn't fork() */
    break;
    case 0:
      /* in the child here: let's dump core */
      abort();
    break;
    default:
      /* in the parent, lets wait for the child's death to prevent zombie
         formation, and then proceed */
      waitpid(childpid, NULL, 0);
  }
}

Of course, this is all untested vaporware, and you are happily
encouraged to check out the man pages on fork, abort and waitpid and
include the proper header files.
