Description:
------------
when creating an object on the globals array, referancing its members to a variable does not work properly.

it works as expected in normal arrays.



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

 class a
 {
  var $r;
  function a()
  {
   $this->r=1;
  }


 }

 $GLOBALS["a"]=&new a();
 $a=&$GLOBALS["a"]->r;

 print($a);
  $GLOBALS["a"]->r=2;
//should print 2, instead prints 1
 print($a);

?>


Expected result:
----------------
12

Actual result:
--------------
11
