Description:
------------
If you create two objects which contain a reference to the  
other object, none of both __destruct() functions will be 
called.  
  
Configure: './configure' '--with-mysql' '--with-xsl'  
'--with-sqlite' '--enable-sockets' '--with-mysql-sock'  
'--with-gd' '--with-dom' '--with-apxs2=/usr/sbin/apxs2'  
'--with-zlib'   

Reproduce code:
---------------
class A {
	function __construct()	{
		print "Construct A!";
		$this->other = new B( $this );
	}
	function __destruct() {
		print "Destruct A!";
	}
}

class B {
	function __construct( A $obj ) {
		print "Construct B!";
		$this->other = $obj;
	}
	function __destruct() {
		print "Destruct B!";
	}
}
new A();

Expected result:
----------------
Construct A!Construct B!Destruct A!Destruct B! 

Actual result:
--------------
Construct A!Construct B!
