PHP Bug Type:     Arrays related
Bug description:  foreach (var as &var construct overwrites last element of 
array

Description:
------------
it looks like foreach (var as &val) syntax leaves a refecence alive after
the last iteration. calling a subsequent foreach (var as val) (same
variable being used to iterate, but not as a ref now), the reference from
the first foreach is used to update the array...

Reproduce code:
---------------
<?php

$array = array(1, 2, 3);

foreach ($array as &$a) {
}
unset($a);
var_dump($array);
foreach ($array as $a) {
}

var_dump($array);


Expected result:
----------------
$array unchanged

Actual result:
--------------
$array changed.
