Description:
------------
get_declared_classes() and get_declared_interfaces() print every item twice!!!
at windows 2003 and iis fastcgi!

and get_defined_functions() is print every item twice too with unreadable codes(error code).
 


Test script:
---------------
$f = get_defined_functions();
echo '<pre>';
print_r($f['internal']); 
print_r(get_declared_classes());
print_r(get_declared_interfaces());

Expected result:
----------------
Array
(
    [0] => Traversable
    [1] => IteratorAggregate
    [2] => Iterator
    [3] => ArrayAccess
    [4] => Serializable
    [5] => RecursiveIterator
    [6] => OuterIterator
    [7] => Countable
    [8] => SeekableIterator
    [9] => SplObserver
    [10] => SplSubject
    [11] => Reflector
    )


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

(
    [0] => Traversable
    [1] => IteratorAggregate
    [2] => Iterator
    [3] => ArrayAccess
