--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
More clarification:

    54    /* The second write access should not invoke the handler.  */
    55    crasher (page);
    56    /* Check that the handler was called only once.  */
    57    if (handler_called != 1)
    58    {
    59      __builtin_printf ("handler_called == 1\n");
    60      exit (1);
    61    }

The segfault happens at line 55.
