Description:
------------
PHP version is actually 5.3.0-alpha2, but it was not in the list.

Was running a small script and then installed APC and then it was crashing.  Narrowed it down to using the syntax:

$a = function () use ($vars) {
   ...
};

*OR*

callbac_func(function () use ($vars) {
    ...
});

If you do not use the "use ($vars)" portion, it would not crash.

Reproduce code:
---------------
<?php
$a = "Hello, Closures!";
$b = function() use ($a) {
    echo $a;
};
?>

Expected result:
----------------
Hello, Closures!

Actual result:
--------------
Program received signal SIGABRT, Aborted.
