Description:
------------
if AN ARRAY WITHIN AN OBJECT is used in "a straight manner" in the foreach() loop,  with the references to its values[poor English, see the SECOND foreach() in the submitted code to understand I mean],

the last value in the array will be REPACED with the second last one ACCIDENTALLY, WITHOUT ANY ASSIGNMENT OPERATION.



Reproduce code:
---------------
<?php
    class myc{  public $a;  }
    $o3->a  =  Array(  11,  22  );

    //loop ONE
    foreach(  $o3->a  as  $k =>  $v  )
        echo $v. ' ';     //EXPECT 11 22 ,  CORRECT OUTPUT
    echo "\n=========\n";

    //loop TWO notice the reference & sign for $v
    foreach(  $o3->a  as  $k => & $v  )
        echo $v. ' ';    //EXPECT 11 22 ,  CORRECT OUTPUT
    echo "\n=========\n";

    //loop THREE
    foreach(  $o3->a  as  $k => $v  )
        echo $v. ' ';    //EXPECT 11 22 , BUT WRONG OUTPUT: 11 11
    echo "\n=========\n";
?>

Expected result:
----------------
11 22
11 22
11 22

Actual result:
--------------
11 22
11 22
11 11
