serialize() works not correct with cascaded objects in some circumstances  (on PHP 3.0.1x this worked correct !!) :
You have an object whitch contains "normal" variables like integers, strings and also other objects. These other objects also contains integers, strings etc. and again objects:

object 1 --- variable 11
          |- variable 12
          |      :
          |- variable 1x
          |- object 2 --- variable 21
                       |- variable 22
                       |      :
                       |- variable 2x
                       |- object 3 --- variable 31
                                    |      :
                                    |- variable 3x

Under some circumstances the output that serialize() produces does only contain the top-level object (object 1)with its "normal" variables (variable 11 ... variable 1x). The other objects (object 2 and 3) with all there variables are lost.

Could you please try latest snapshot from http://snaps.php.net/ ?
This example code of yours works for me just fine (Linux).

User feedback:
-----------

now I'v got the latest snapshot and it seems that the serialize-bug is
fixed. All my scripts seems to work just fine now (with
Linux/Apache/PHP4.0.4-DEV_DSO). I could not try anything with Win9x,
because I don't have MSVC++ to compile PHP under Windows OS. If anyone
have a compiled version for Windows as ISAPI ".dll" please send it to me
and I'll try.
