Description:
------------
http://bugs.php.net/bug.php?id=19859 seems to be the same, but for PHP5.

When using call_user_func/call_user_func_array, undefined methods are not handled by __call.

Reproduce code:
---------------
<?php
    class MyOverload {
        function __call($method,$args,&$return) {
            return $return = "__call result\n";
        }
    }
    
    overload('MyOverload');
    $obj =& new MyOverload;
    echo $obj->test();
    
    echo call_user_func(array($obj,'test'));

?>

Expected result:
----------------
__call result
__call result

Actual result:
--------------
__call result
Warning:  call_user_func(myoverload::test): First argument is expected to be a valid callback
