Bug description:  setting reference to $this in constructor.

When I want to set reference to $this object gets copied.
In this example $ui_handler contains copy of object $test.
$ui_handler -> data is not reference to $test.
I use CVS 2001-06-24.

<?
class CUI_element {
        var $value;
        function CUI_element($value) {
                global $ui_handler;
                $this -> value = $value;
                $ui_handler -> register($this);         
        }
}

class CUI_handler {
        var $data;
        
        function CUI_handler() {
                $this -> data = false;
        }
        
        function register(&$element) {
                $this -> data = &$element;
        }
};

$ui_handler = new CUI_Handler();
$test = new CUI_Element("test");
$test -> value = "changed";
var_dump($ui_handler -> data); print "<br>";
var_dump($test); print "<br>";
?>

My output:
object(cui_element)(1) { ["value"]=> string(4) "test" } 
object(cui_element)(1) { ["value"]=> string(7) "changed" }
