Bug description:  get_class and debug_backtrace report wrong class forinherited static methods

Description:
------------
When a static function is called in the scope of an extended class, the
static function still thinks it's being called in the scope of the base
class.

I found a similar bug at http://bugs.php.net/bug.php?id=30828 which was
fixed in 5.0.5, but the problem still remains.

Reproduce code:
---------------
<?

class baseClass {
	static function do_get_class() {
		return get_class();
	}
	static function do_backtrace() {
		$backtrace = debug_backtrace();
		return $backtrace[0]['class'];
	}
}
	
class extendedBaseClass extends baseClass {
}

echo extendedBaseClass::do_get_class() . "<br>";
echo extendedBaseClass::do_backtrace() . "<br>";

?>

Expected result:
----------------
extendedBaseClass
extendedBaseClass

Actual result:
--------------
baseClass
baseClass
