Description:
------------
You have a main object which includes some other 
objects. This object is stored in the session. The 
other objects have a reference to the main object. If 
you start a new session these references should point to 
the main object. If you pass the objects to the main 
object in the old style with "&" this works fine. If you 
use the new style without "&" it doesn't work as 
exspected.

Reproduce code:
---------------
The classes:

class CHello
{
        var $store;

        // this doesn't work as exspected
        public function CHello($store)
        {
                $this->store = $store;
        }
/*
        // this works fine
        public function CHello(&$store)
        {
                $this->store =& $store;
        }
*/
        public function hello( )
        {
                $v = $this->store->value;
                echo "Hello World: value is $v. (store id: $this->store)<br>";
        }
}

class CStore 
{
        var $object1;
        var $object2;

        var $value = 0;
}

---------------------------

The first script:

session_start();

$store = new CStore;
$hello1 = new CHello($store);
$hello2 = new CHello($store);

$store->value = 999;
$store->object1 = $hello1;
$store->object2 = $hello2;

echo "store id: $store<br>";

$store->object1->hello();
$store->object2->hello();

session_register("store");

---------------------------

The second script:

session_start();

$store->value = 123;

echo "store id: $store<br>";

echo $store->object1->hello();
echo $store->object2->hello();


Expected result:
----------------
The first script where the objects are generated:
store id: Object id #4
Hello World: value is 999. (store id: Object id #4)
Hello World: value is 999. (store id: Object id #4)

The second script:
store id: Object id #1
Hello World: value is 123. (store id: Object id #1)
Hello World: value is 123. (store id: Object id #1)

Actual result:
--------------
The first script where the objects are generated:
store id: Object id #6
Hello World: value is 999. (store id: Object id #6)
Hello World: value is 999. (store id: Object id #6)

The second script:
store id: Object id #1
Hello World: value is 999. (store id: Object id #3)
Hello World: value is 999. (store id: Object id #5)
