Description:
------------
Broken reset/next functionality after upgrading from PHP 4.4.0 to 4.4.1 when the array is passed from the global scope.

The code below results in an infinite loop


Reproduce code:
---------------
<?
 
$Buffer["key1"] = "value1";

Process();

function Process() {
  global $Buffer;
  for (reset($Buffer); $key=key($Buffer); next($Buffer)) {
    print "processing key: $key\n";
  }
  print "done\n";
}

?>


Expected result:
----------------
processing key: key1
done

Actual result:
--------------
processing key: key1
.
. infinite loop
.
processing key: key1
