It missing a initialized checking when accessing member variable.
I've sent a patch here: https://github.com/php/php-src/pull/123

Also a short note,
This problem can be worked around by calling the parent constructor before 
accessing any members.

Description:
------------
Hello,

I found a way to reproduce a segfault on at least linux but possibly on other 
OS'es as wel.

It is very simple to reproduce:
 1 overload the DateInterval in a new class.
 2 overload the constructor
 3 use one of the member variables.

[Sat Jul 07 17:46:32 2012] [notice] child pid 5775 exit signal Segmentation 
fault (11)

I tested with PHP 5.4.4 and it is there, but it also exists in PHP 5.3

Test script:
---------------
<?php

class Crasher extends DateInterval {

        public function __construct($time_spec) {
                echo "Yes i did it, with the next statement it gives a 
segfault\n";
                // It doesn't matter if we take the y parameter or any other.
                $this->y = 3;
        }

}

$c = new Crasher('blah');

?>


Expected result:
----------------
Yes i did it, with the next statement it gives a segfault
Segmentation fault
