Description:
------------
In 4.4.1, when you unserialize an array, then attempt to globalize it within a function, and then pass it to an internal array function such as next or key, it does not work as it was in 4.3.10 or how it functions in PHP 5.0.5.  This functions as expected in 4.3.10 and 5.0.5.  The documentation clearly states you are not to use next(&array) or key(&array) when using references, which is why this is not used.

Reproduce code:
---------------
<?
$ar = array(array('ID' => 'BOB'),  array('ID' => 'GEORGE'),  array('ID' => 'JOHN'));

$ser = serialize($ar);
$arn = unserialize($ser);

print_r($arn) . "\n\n"; 

function breakPHP() {
    global $arn;
    for ($i = 0, reset($arn); ($key = key($arn)), (isset($key)); next($arn), $i++) { 
        print "$key ... " . $arn[$key]['ID'] . "<br>\n";
        if ($i > 5) {
            print "we looped";
            exit;   
        }       
    }
}
breakPHP();
?>

Expected result:
----------------
Array
(
    [0] => Array
        (
            [ID] => BOB
        )

    [1] => Array
        (
            [ID] => GEORGE
        )

    [2] => Array
        (
            [ID] => JOHN
        )

)
0 ... BOB<br>
1 ... GEORGE<br>
2 ... JOHN<br>

Actual result:
--------------
Array
(
    [0] => Array
        (
            [ID] => BOB
        )

    [1] => Array
        (
            [ID] => GEORGE
        )

    [2] => Array
        (
            [ID] => JOHN
        )

)
0 ... BOB<br>
0 ... BOB<br>
0 ... BOB<br>
0 ... BOB<br>
0 ... BOB<br>
0 ... BOB<br>
0 ... BOB<br>
