Description:
------------
Classes which implement the Serializable interface and were serialized and unserialized and than used inside a thread crashes PHP inside the run() function.


Test script:
---------------
class Test implements Serializable
{
	public function serialize()
	{
		return serialize( array() );
	}
	
	public function unserialize( $serialized )
	{
		$cfg = unserialize( $serialized );
	}
	
	public function foo()
	{
	}
}

$test = new Test();

// Does the magic:
$test = unserialize( serialize( $test ) );

class MyThread extends Thread
{
	private $test;
	
	public function __construct( $test )
	{
		$this->test = $test;
	}
	
	public function run()
	{
		$this->test->foo();
	}
}

$thread = new MyThread( $test );
$thread->start();
$thread->join();


Expected result:
----------------
Normal workflow

Actual result:
--------------
Memory access violation
