The script below causes a fatal error on git master. Currently works as expected on PHP 5.3 - 5.6.

Perhaps related to https://bugs.php.net/bug.php?id=62171

Test script:

<?php
$arr = new \ArrayObject(array('a'));
foreach( $arr as $item );
var_dump($arr->getArrayCopy() === array('a'));

An more simpler reproduce case is:

<?php
$arr = range(1, 2);
foreach($arr as &$item ) {
    var_dump($arr === array(1, 2));
}
?>
