Hello,

This is partially taken from comments I made on someone else's bug report #20449, as I don't know if it's the same or not.

Problem : When a session is saved, included objects are not.

I have setup a small test platform, with custom session handlers to a database, and DBMS in debug mode.

When I force a session write before the end of the script, I get the _whole_ session var serialized.

When I force a sess_write_close at the same place, I get a _truncated_ serialized session var (objects missing, but vars still there)

When I let things behave normally (not forcing write), I get a _truncated_ serialized session var (objects missing, vars present)

When I try to bypass arguments passed to my sess_write function by using $PHPSESSID, and serialize($session), I get an error stating that $session has been destroyed.

Thus, I have an hypothesis : The objects inside the session var are destroyed _before_ the serialization occurs, leading to a truncated result. 

regards,
