Description:
------------
(sorry for english...)

here is my fifth segmentation fault in PHP 5...

Reproduce code:
---------------
<?
class test { }

class thamer {

	public $test;

	public function __construct() {
		$this->test = new test; /* An entire mystery, without this code, no segmentation fault */
	}

	public function __destruct() {
		fuck();
		/*
			If you don't like "fuck()" and if you want a segfault, you can try with everything that raise a fatal error. Some examples :
			- trigger_error("thamer", E_USER_ERROR);
			- unset(self::$thamer);
			Warning : no fatal error, no segfault :)
		*/
	}

}

$test = new thamer;
?>

Expected result:
----------------
A fatal error (no segmentation fault...).

Actual result:
--------------
[Mon Sep 13 22:07:42 2004] [error] PHP Fatal error:  Call to undefined function fuck() in /www/test.php on line 13
/www/test.php(13) : Fatal error - Call to undefined function fuck()
