Description:
------------
PHP 4.4.1 drops into an infinite loop 
(lots of '1 => one' gets printed). This 
problem doesn't exist in PHP 5.1.1 and 
in PHP version prior 4.4.1.

Reproduce code:
---------------
<?php

$a = array('1'=>'one','2'=>'two','3'=>'three');

function test(){
    global $a;
	for( reset($a); $key = key($a); next($a)) {
		echo "$key => $a[$key]\n";
	}
}
test();
?>

Expected result:
----------------
1 => one
2 => two
3 => three

Actual result:
--------------
1 => one
1 => one
1 => one
1 => one
1 => one
1 => one
1 => one
1 => one
1 => one
1 => one
1 => one
1 => one
1 => one
