Bug description:  usort, uasort, uksort fail every other time

usort, uasort and uksort all fail to sort an array 
properly every other time they are called, unless the 
array is reset() after each call.

This is a snippet from a class that fails every other time 
it is called.

    var $sort_field;

    function cmp ($a, $b) {
        return ($a[$this -> sort_field] > $b[$this -> 
    function sort_records ($sort_field) {
        $this -> sort_field = $sort_field;
        uasort ($this -> record_data, array($this, "cmp"));
