The following example results in a segfault in PHP 5.  It's OK in 4.3.0.

<?
	function f($v)
	{
		print("$v\n");
	}

	//OK (control)
	$Function = "f";
	$Function("success");

	//OK (fatal error)
	//$Function = "f2";
	//$Function("success");

	//Segfault (should be fatal error)
	$Function = NULL;
	$Function("success");
?>
