Description:
------------
Test script will valgrind (and show a leak). This issue is closely related to bug #72215, in that
both are caused by us not computing the final return value (and backing it up) before the finally.
Test script:
---------------
<?php
function &test() {
$a = [];
try {
return $a[0];
} finally {
$a[""] = 42;
}
}
var_dump(test());
