Description:
------------
There is a backwards incompatible change in trunk in that function can no longer have parameters with a name equal to the one of some superglobal.

This should either be fixed with the previous behavior (the parameter shadows the superglobal) or documented in UPGRADING.

Test script:
---------------
$ php -d error_reporting=-1
<?php
function a($GLOBALS) {
        $GLOBALS['h'] = 8;
}
$g = null;
a($g);
var_dump($h);

Expected result:
----------------
On 5.3:

Notice: Undefined variable: h in - on line 7
NULL


Actual result:
--------------
On trunk:

Fatal error: Cannot re-assign auto-global variable GLOBALS in - on line 2
