Forget to put run code...
This is to insert after test class definition.
$original = new test;
$original->append(new bidon());
$original->append(new bidon());
$cloned2 = clone $original;

I don't see any problems:
<?php
class test extends ArrayObject {
public $pub = 1;
public function __clone() {
$this->pub = "cloned";
}
}
$a = new test;
$b = clone $a;
var_dump($a->pub);
var_dump($b->pub);
?>
int(1)
string(6) "cloned"
Did you even try to run your code?
I doesn't work at all as you didn't instanciate the objects.

Description:
------------
When a __clone() function is defined for a class that extends
arrayObject from SPL, there is no way to clone the objects contained in
arrayObject.
If you do same code for class not extending the SPL arrayObject but any
other objectContainer, there is no problem.
Reproduce code:
---------------
class bidon {
public $foo = "bidon 1";
}
class test extends ArrayObject {
public $pub = 1;
public function __clone() {
$this->pub = "cloned";
foreach ($this as $k=>$item) {
$this[$k]= clone $item;
$this[$k]->foo++;
}
}
}
if($original === $cloned2) {
echo "bad master clone# $original $cloned2<br>";
} else { echo "good master clone<br>";}
foreach ($original as $k=>$obj) {
if($original[$k] === $cloned2[$k]) {
echo "bad clone childs# $original[$k] $cloned2[$k]<br>";
} else { echo "good child clone<br>";}
}
Expected result:
----------------
good master clone
good child clone
good child clone
Actual result:
--------------
good master clone
bad clone childs# Object id #7 Object id #7
bad clone childs# Object id #2 Object id #2
