Obviously a flaw in the way an object is identified in the engine/in the
serializer.
Since the cloned objects only live for the time of serialization, both have the
same object handle and will be identified as the *same*.
Not sure why unserialize barfs on it, though.

@slusarz: Github changed the Gist URLs to include the owner's name too. I guess
they didn't consider users having number-names while doing that ^^

Strange... Since that is the link github provides when you click on "share".
Anyway, try this instead:

Description:
------------
When using clone in a Serializable serialize() method, the first object is
correctly cloned/saved. However, all subsequent calls to serialize() in the
same script access will have incorrect serialized representations of the cloned
object.
Using var_dump, it appears that clone is reusing the same object ID when the
object is cloned.
I can verify that removing the 'clone' keyword in the test script causes the
script to run correctly.
Test script:

https://gist.github.com/4709613
Expected result:
----------------
See gist for expected value.
For the record, the serialized value of the A object is as follows:
O:1:"A":1:{s:1:"a";a:2:{i:0;C:1:"B":24:{O:1:"C":1:{s:1:"c";i:1;}}i:1;C:1:"B":4:{r:4;}}}
Actual result:
--------------
See gist for actual value.
FWIW, running with --enable-debug produces this message:
