Description:
------------
A bug occur after doing a natsort and an array_reverse.

after the natsort all seem to be good but after array_reverse not.

If we don't use natsort all work fine.



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

$test = array ("/", "/mnt", "/tmp");

natsort($test);
print_r($test);
$test = array_reverse($test);

print_r($test);

?>

Expected result:
----------------
Array
(
    [0] => /
    [1] => /mnt
    [2] => /tmp
)

Array
(
    [0] => /tmp
    [1] => /mnt
    [2] => /
)

Actual result:
--------------
Array
(
    [0] => /
    [1] => /mnt
    [2] => /tmp
)

Array
(
    [0] => /tmp
)
