Description:
------------
If I declare a reference variable (&$value) and use it in a 'foreach' and then I reuse it in the same loop like a normal variable ($value), I have an unexpected result, array is modified!
Note that using another variable in the second 'foreach' the result is Ok.


Reproduce code:
---------------
<?php
        $v = array (1,2,3);
        foreach($v as &$value);
        print_r($v);
        foreach($v as $value);
        print_r($v);
?>


Expected result:
----------------
Array
(
    [0] => 1
    [1] => 2
    [2] => 3
)
Array
(
    [0] => 1
    [1] => 2
    [2] => 3
)


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