Operating system: 
PHP version:      5.3.1
PHP Bug Type:     Class/Object related
Bug description:  call_user_func_array, __call and references

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.
