Glancing at the backtrace on my local machine this has to do with clone call.

Description:
------------
php-cgi segfaults when trying to encode a class which extends json_serializable.
At least this happens when the json_serialize method unsets a variable declared in the class.

Example in:
http://3v4l.org/TSgMV

---
From manual page: http://www.php.net/class.jsonserializable
---



Test script:
---------------
class C implements JsonSerializable {
    var $a = 'lol';
    var $b = 'fa';
    public function jsonSerialize() { 
	$aux = clone($this);
        unset($aux->a);
        return $aux; 
    }
}
echo json_encode(new C()); //Ka-boom!!

Expected result:
----------------
The object json-encoded only with var $b.

Actual result:
--------------
Segmentation fault.
