(_not_ a "segment fault").

man abort:

NAME
       abort - cause abnormal process termination

SYNOPSIS
       #include <stdlib.h>

       void abort(void);

DESCRIPTION
       The abort() function first unblocks the SIGABRT signal, and then raises
       that signal for the calling process (as though  raise(3)  was  called).
       This  results  in  the  abnormal  termination of the process unless the
       SIGABRT signal is caught and the signal handler does  not  return  (see
       longjmp(3)).
