#32976 [Opn->Fbk]: (Un)serialize destroys references in a tree like class structure

I'm using a tree like structure in which every node has a reference to its parents and its children. When deserializing, the reference becomes corrupted (or rather it disappears). Look at the url below: http://sportlaan.adsl.utwente.nl/webstorage/index.php The first time a session is created with the default tree, notice that the nodes link to eachother. When you click on the upload link at the left directory tree (below the debug output) you'll see the script stops with an error complaining about its parent not being an object. This should be the exact same structure as when starting the script. Btw, kill the session using: http://sportlaan.adsl.utwente.nl/webstorage/index.php?clear=1 I've tested the code on the PHP 4.3.*something* engine as well and that one handles it perfectly - the references are restored using the serialize and unserialize calls. Btw, I saw the bug report on: http://bugs.php.net/bug.php?id=27120 This seems (by description) pretty much the same bug as reported before - what puzzles me though is that the old bug is from the old PHP5 CVS version whereas I am already using the stable 5.0.4. So its either not the same bug or the bug reappeared again...
