without any problem.

private $b;
public function setB($b) {
$this->b = $b;
}
public function serialize() {
return serialize($this->b);
}
public function unserialize($s) {
$this->b = unserialize($s);
}
}
class B {
private $a;
public function __construct($a) {
$a->setB($this);
$this->a = $a;
}
}
$a = new A();
$b = new B($a);
var_dump(serialize($b));
?>
Expected result:
----------------
The string of the serialized object.
Actual result:
--------------
Apache crash or cli segfault.
