Description:
------------
I use a code like below on a server with php 5.1.6 for long, and the expected 
result below is the ACTUAL output of the code. 

Recently I have a new server running 5.3.3 and no luck. 

The point is the class instance is not able to be referenced when it runs to 
__destruct(). I use some functions to help object cleaning easier.

Any comment or help will be appreciated.

Test script:
---------------
class Database {
function __destruct() {
echo "Destroyed Database\n";
}}

class Session {
private $db;
function __construct() {
$this->db = new Database();
}
function __destruct() {
echo "Destroyed Session\n";
check();
} }


$sess = new Session();
check();

die();

function check(){
global $sess;
if(isset($sess)) echo "yes\n";
else echo "no\n";
}


Expected result:
----------------
yes
Destroyed Session
yes
Destroyed Database


Actual result:
--------------
yes
Destroyed Session
no
Destroyed Database
