Isn't this "won't fix" then?

The problem is clear but unfixable.
$a[0] is compiled into ZEND_FETCH_DIM_R that increments reference count
of $a[0] this reference should be decremented back on $a[0] usage, but
because of exception this statement is never reached.

Description:
------------
The code below causes two small memleaks.
Reproduce code:
---------------
<?php
function err($errno, $errstr, $errfile, $errline) {
throw new Exception($errstr);
}
set_error_handler("err");
function foo() {
$a = array("aaa");
foreach ($a as $o) {
//$this->prop[$a] = foo($undef2); //no leak
//$this->prop["aa"] = foo($undef2); //no leak
$this->prop[$a[0]] = foo($undef2); //leak
}
}
try {
foo();
} catch (Exception $e) {
var_dump($e->getMessage());
}
?>
Actual result:
