Thank you for your bug report.
Is there a problem with this other than that the serialization string
is different? Do objects $a and $b have different behavior?

And one more wrong work Example:
$a = new stdClass;
$a->v2 = &$a;
$a->v1 = $a;
echo serialize($a)."\n";
$b = &unserialize(serialize($a));
echo serialize($b);
Expected result:
----------------
O:8:"stdClass":2:{s:2:"v2";R:1;s:2:"v1";r:1;}
O:8:"stdClass":2:{s:2:"v2";R:1;s:2:"v1";r:1;}
Actual result:
--------------
O:8:"stdClass":2:{s:2:"v2";R:1;s:2:"v1";r:1;}
O:8:"stdClass":2:{s:2:"v2";r:1;s:2:"v1";r:1;}
