DatePeriod, as most others Date* objects, does not have proper
serialization
handler, this is the cause of the segfault.

Description:
------------
PHP 5.3.2-1 with Suhosin-Patch (cli) (built: Mar 14 2010 00:09:57
Standard Debian packages
Segfault when trying to construct a DatePeriod with an unserialized
DateInterval.
Test script:
---------------
<?php
$start = new DateTime('2003-01-02 08:00:00');
$end = new DateTime('2003-01-02 12:00:00');
$diff = $start->diff($end);
$p = new DatePeriod($start, $diff, 2);
$diff_s = serialize($diff);
$diff_un = unserialize($diff_s);
// Will segfault
$p = new DatePeriod($start, $diff_un, 2);
Expected result:
----------------
No Segfault
Actual result:
