I've discovered one more crash and reported here of the same type:
http://bugs.php.net/bug.php?id=46754

Heres another one with __call():
<?php
	class Test
	{
		public function __call($call, Array $args)
		{
			call_user_func_array(Array($this, $call), $args);
		}
	}

	$test = new Test;
	$test->crash();
?>

This one is a little odd, however I get a memory_limit error but straight after it crashes:
<?php
	start:
	{
		$a = function($b) use($a)
		{
			$a();
		};
	}

	goto start;
?>

Closing as duplicate of bug #64280. It's newer, but has more discussion.
