I haven't found way to attach patches here, so it's available on my
web: http://www.cihar.com/misc/php-unserializer.patch

Description:
------------
Unserializing of numbers > MAX_INT is wrong. That's because php uses
long internally for storing ints but int is used in unserializing.
Attached patch fixes this issue.

Reproduce code:
---------------
<?php
echo unserialize(serialize(2147483648));
?>


Expected result:
----------------
2147483648

Actual result:
--------------
-2147483648
