Bug description: segfault under Apache when using bad cleanup function

Under PHP4, registering a shutdown function that contains invalid PHP code (such as a call to a non-existent function) causes the server process to segfault.
Here is a scriptlet which reproduces the problem:

<?
   function close_socket() {
      close($fd);
   }
   register_shutdown_function(close_socket);

?>

I stumbled on this quite accidentally--of course, I meant to use fclose() instead of close(). Still, it seems that PHP should handle this better than by causing a segfault. :)
