Description:
------------
A static function in the base class (A) can execute a protected function in a derived class (B).

If the same function is called from outside of class A the PHP Fatal error occurs as excepted.

The error also occurs with the CVS Snapshot php5-STABLE-200507211237 compiled with ./configure && make

Reproduce code:
---------------
<?php
class A {
        public static function test()   {
                $a = new B();
                $a->test2(); # why does this work?
        }
}
class B extends A {
        protected function test2()      {
                echo "B: test2 \n";
        }
}

A::test();

$b = new B();

# call a protected function -> PHP Fatal error as excepted:
$b->test2(); 
?>


Expected result:
----------------
PHP Fatal error:  Call to protected method B::test2() on line  5
