Ok, I've always worked with crossed references, what's wrong with them?
It's forbiden in php? I think it's a huge limitation, I would have to do
garbage collection myself and I only have debug_zval_dump : it's really
not very usefull but for debugging purpouses. And I have to choose
between true (&) references and "php" references because if both are
used, refcount is no more significatif... Can you give me an advice?

You've created a cyclic reference and they can't be destroyed until the
script has ended.

Description:
------------
Garbage collection works in an unexpected way for me,
when there're crossed references. I discovered it working with large 
databases, Apache crashes sometimes : the thread hangs and 
after /etc/init.d/apache2 restart, it continues working.

Another thing : the only way to get track of references is 
debug_zval_dump (of course it can be done manually) and huge strings 
must be parsed. Further, when mixing true (&) and "php" references 
it's no more possible... or is it?

Only a tought...

Thanks

Reproduce code:
---------------
class a {
        public function __destruct() {
                echo 'destr<br>' ;
        }
}

$a = new a ;
$a -> v = new a ;
$a -> w = new a ;
$a -> v -> w = $a -> w ;
$a -> w -> v = $a -> v ;

unset ($a) ;
echo 'fin<br>' ;
exit ;

Expected result:
----------------
destr
destr
destr
fin

Actual result:
--------------
destr
fin
destr
destr
