Bug description:  cloning and  and references inside the objects

Description:
------------
I encountered a problem similar to the bug #27268
http://bugs.php.net/bug.php?id=27268

The attribut b of the cloned object is still pointing to the attribut of
its original object. So changing the attribut in the cloned object also
changes the attribute in the original object.

Reproduce code:
---------------
<?php

class a {
    protected $a = array();
    protected $b = '';
    public function __construct($b) { $this->b = $b; $this->a['f'] =
&$this->b; }
    public function setB($b) { $this->b = $b; }
    public function printB() { echo __CLASS__ . $this->b . '/' .
$this->a['f'] ."\n"; }
    public function __clone() { unset($this->a['f']); $this->a['f'] =
&$this->b; }
}

$x1 = new a(5);
$x2 = clone $x1;
$x2->setB(7);
$x1->printB();
$x2->printB();



Expected result:
----------------
a5/5
a7/7

Actual result:
--------------
a7/7
a7/7
