Description:
------------
The way how call_user_func_array() passes arguments to the function by reference has been broken in PHP versions 5.3.1, 5.2.11, 5.2.12 in conjunction with __call().

See http://php.net/manual/en/function.call-user-func-array.php - Note: Referenced variables in param_arr are passed to the function by a reference, others are passed by a value. In other words, it does not depend on the function signature whether the parameter is passed by a value or by a reference.




Reproduce code:
---------------
class Test
{
	public function __call($name, $args)
	{
		$args[0]++;
	}
}



$viaRef = 1;
call_user_func_array(
	array(new Test, 'method'), 
	array(& $viaRef)
);
echo $viaRef;


Expected result:
----------------
2


Actual result:
--------------
PHP 5.3.1, 5.2.11, 5.2.12 returns „1“, other versions „2“ as documented.
