Description:
------------
A certain object reference situation that my code depends on has been broken in 5.2.1 on *windows*.  It works on my linux production server running 5.2.1.

Thanks.

Reproduce code:
---------------
class Foo 
{
   private $params = array();
			
   function __set($name, $value){
     $this->params[$name] = $value;
   }
   
   function &__get($name){
     return $this->params[$name];
   }			
}

$foo = new Foo();
$ref =& $foo->bar;
$ref = "This is a test";
print($foo->bar);

Expected result:
----------------
It should print out "This is a test"

Actual result:
--------------
On windows, nothing is printed out.  $foo->bar is not set.
