Description:
------------
Segmentation fault is segmentation fault, should never happen, even thou the code is stupid.

Not sure how to describe this problem, guess the example speak for it self.
Short, and quite funny, example provided.

Reproduce code:
---------------
<?php
    class foo extends DOMDocument {
        function __construct() {
            $this->obj = $this;
            $this->obj = $this->obj->foobar;
        }
    }
    new foo;
?>


Actual result:
