Description:
------------
When the magic __call() form extends,It can't call the private or protected 
function of child class, and worse, it would have been to call its own.
But I watch others magic like __set(), __get(), they will not be affected for 
work in child.

Test script:
---------------
class superTest {
        public function __call($func, $param) {
                echo "Is __call", PHP_EOL;
                $this->$func($param);
        }
}
final class test extends superTest {
        private function hello($i) {
                echo "hello,world - $i[0]", PHP_EOL;
        }
        /** It will call hello() , only once, everything is fine
        public function __call($func, $param) {
                echo "Is __call in Child", PHP_EOL;
                $this->$func($param);
        } */
}

$test = new test();
$test->hello(1);

Expected result:
----------------
Is __call
Hello,world - 1

Actual result:
--------------
Is __call
Is __call
Is __call
Is __call
Is __call
Is __call
Is __call
...
// stack exception
