Bug description:foreach-statement manipulates array (in a special case)

Description:
------------
The test script manipulates the last entry of $my_array instead of all or
leaving everything as it is.

my php version: 5.2.10

Test script:
---------------
<?
$my_Array[] = 'a';
$my_Array[] = 'b';
$my_Array[] = 'c';
$my_Array[] = 'd';

echo '<pre>1:' . print_r($my_Array, true) . '</pre>';

foreach($my_Array as &$value){
}

echo '<pre>2:' . print_r($my_Array, true) . '</pre>';

foreach($my_Array as $value){
}

echo '<pre>3:' . print_r($my_Array, true) . '</pre>';
?>

Expected result:
----------------
3:Array
(
    [0] => a
    [1] => b
    [2] => c
    [3] => d
)

Actual result:
--------------
3:Array
(
    [0] => a
    [1] => b
    [2] => c
    [3] => c
)
