#48789 [NEW]: foreach($a as $k => &$v) gives unexpected behavior

Bug description:  foreach($a as $k => &$v) gives unexpected behavior

Description:
------------
The last foreach seems to corrupt $rows_unsorted. The last var_dump() in
the log reports false.

Reproduce code:
---------------
    $rows_unsorted = array();
    for ($i = 0; $i < 4; $i++)
    {
        array_push($rows_unsorted, array("apa" . $i));
    }

    $rows_index = array();
    foreach ($rows_unsorted as $k => &$row)
    {
        array_push($rows_index, sprintf("%03d_%d", strlen($row[0]), $k));
    }

    for ($i = 0; $i < 4; $i++)
    {
        var_dump($rows_unsorted[$i]);
    }

    foreach ($rows_index as $idx)
    {
        list ($len, $rowOffs) = split('_', $idx);
        $row = false;
        $row = $rows_unsorted[0 + $rowOffs];

        var_dump($row);
    }

Expected result:
----------------
I was expecting all values in $rows_unsorted to have been dumped.
