PHP Bug Type:     Session related
Bug description:  Pointer to item in $_SESSION superglobal causes troubles

Description:
------------
Seems that once you've declared a pointer to one of the items in session
superglobal any other assignment of a variable to that session item is
alwayys treated as a pointer.

Tested on various versions of php 4.3 till 4.3.1
Register globals are OFF
php 5.0.4 having same error


Reproduce code:
---------------
session_start();
for ($i = 0; $i < 2; $i++)
{
        $_SESSION['storage'][$i] = array('items'=>$i);
}
$items = count($_SESSION['storage']);
for ($i = 0; $i < $items; $i++)
{
        $pointer = &$_SESSION['storage'][$i];
//      unset($pointer);        // Uncomment me to let me work properly
}
$gitems = $_SESSION['storage'];
foreach ($gitems as $key=>$val)
{
        $gitems[$key]['foo'] = time();
}


Expected result:
----------------
$_SESSION = Array
(
    [storage] => Array
        (
            [0] => Array
                (
                    [items] => 0
                )
            [1] => Array
                (
                    [items] => 1
                )
        )
)

Actual result:
--------------
$_SESSION = Array
(
    [storage] => Array
        (
            [0] => Array
                (
                    [items] => 0
                    [foo] => 1118913576
                )

            [1] => Array
                (
                    [items] => 1
                    [foo] => 1118913576
                )
        )
)
