Description:
------------
Passing arguments to __clone() causes a memory leak. (I 
know this is invalid.)

Reproduce code:
---------------
class foo {
    function __clone() {}
}

$a = new foo;
$b = $a->__clone('bad argument');

Expected result:
----------------
No leaks.

Actual result:
--------------
