Bug description:  Special keyword 'self' inherited in child classes

Description:
------------
Special keyword 'self' represents the parent class instead of the child
class when it is used in an inherited method of the parent class.

Reproduce code:
---------------
class Foo {
        const NAME = 'Foo';
        static public function display() {
                echo self::NAME;
        }
        static public function getInstance() {
                $instance = new self;
                return $instance;
        }
}

class Child extends Foo {
        const NAME = 'Child';
}

echo('Class constant: ');
Child::display();
echo('<BR>Object class: ');
echo(get_class(Child::getInstance()));

Expected result:
----------------
Class constant: Child
Object class: Child

Actual result:
--------------
Class constant: Foo
Object class: Foo
