Bug description:Closure->bindTo plus $this reassign = corruption

Description:
------------
I just found the bindTo method on a Closure, a started to play with it. I
found 
out I can get some serieusly strange behaviour by re-assigning $this.
Somehow I 
end up with one variable pointing to different objects?

Test script:
---------------
From: http://3v4l.org/bp598#v540

<?php

class A
{
        public $a = 'public';
}

$m = function (){
        $x =& $this;
        $x = new stdClass;
        var_dump($this, $this->a);
};

$a = new A;
$m = $m->bindTo($a);
$m();

Expected result:
----------------
* Cannot re-assign $this OR
* 'stdClass' + Notice OR
* 'A' + 'public

Actual result:
--------------
object(stdClass)#1 (0) {
}
string(6) "public"
