Bug description:Negative intervals segfault
Description:
------------
Creating an interval with a "negative duration" (i.e., "start" date
precedes "end" date) creates what appears to be a valid DateInterval
object, but any attempt to work with the object results in a segfault.
Test script:
---------------
<?php $a = new DateInterval("2008-05-11T15:30:00Z/2007-03-01T13:00:00Z");
var_dump($a); ?>
Expected result:
----------------
At a minimum, "Not crashing". Ideally, a DateInterval object with a
negative duration, but I don't know of ISO-8601 allows those.
Actual result:
--------------
(gdb) r -r '$a = new
DateInterval("2008-05-11T15:30:00Z/2007-03-01T13:00:00Z"); var_dump($a);'
Program received signal SIGSEGV, Segmentation fault.
