New Comment:
on windows 7 + apache2 + php 5.3.6
apache crashes when
$cl = clone $dateIntervalObject;
in any scope, in any function, on an empty page too.
i tried to provide a backtrace but something goes wrong
i can't convert the generated .dmp file to a readable dump to attach
here

Did you forget to attach the script?

This patch causes issues. If I try the attached script I end up in an
infinite loop.

The following patch implements the logic to clone DatePeriod and
DateInterval objects and also includes a test case:

Description:
------------
I am unable to clone an object of type DateInterval or DatePeriod. The
clone appears to be an empty object.
I've looked in the source and the code to clone the objects seem to be
missing from both date_object_clone_interval() and
date_object_clone_period().
Reproduce code:
---------------
$dateInterval1 = new \DateInterval('P1D');
$dateInterval2 = clone $dateInterval;
var_dump($dateInterval1);
var_dump($dateInterval2);
Expected result:
----------------
$dateInterval2 should be a clone of $dateInterval1.
Actual result:
--------------
$dateInterval1 works as expected, but $dateInterval2 appears to be an
empty object.
