code to reproduce should be like:
<?php
$array = array(1, 2, 3);
foreach ($array as &$a) {
}
var_dump($array);
foreach ($array as $a) {
}
var_dump($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.
