Description:
------------
When using next() on a referenced array, the internal pointer is not
moved at all.

Reproduce code:
---------------
function &getEach(&$a)
{
        if(($elem = current($a)) !== FALSE)
        {
                $k = key($a);
                next($a);
                return $a[$k];
        }
        return false;
} 

$alist = array("a", "b", "c");
for(reset($alist); $yup =& getEach($alist);)
{
 echo &yup;
}

Expected result:
----------------
abc

Actual result:
--------------
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(etc)
