Description:
------------
In case protected method overrides a private one. PHP may bypass protected method accessibility check.

Test script:
---------------
<?php
class A {
        private function f() {
                return "A";
        }
}
class B extends A {
        protected function f() {
                return "B";
        }
}
$b = new B();
try {
        var_dump($b->f());
} catch (Throwable $e) {
        echo "Exception: ", $e->getMessage(), "\n";
}
?>


Expected result:
----------------
Exception: Call to protected method B::f() from context ''

Actual result:
--------------
string(1) "B"
