Clarification:
I am not trying to load a session between versions of PHP!
The bug happens when using PHP 4.0.4pl1, and the backtrace is generated from that.
I have however -- to test that it was the serialization that was buggy under 4.0.4pl1
-- created the same session in 4.0.1pl2 and tried to load it inder 4.0.4pl1,
succesfully.
So whenever I use 4.0.4pl1 in apache it segfaults at that point in then application
---------------------------------------------------------------------------

I get this consquently with 4.0.4+ (tried latest on snaps.php.net)
This happens while unserializing, but seems to be caused by a bad serialization --
this has been tested by serializing with 4.0.1pl2 and unserializing with 4.0.4pl1 --
no problems. The other way around ofcourse crashes.
Here's the bt from the segfault

Here's a working serialization:

And here is the segfaulting one:

These are done at the exact same time in the "app".
Kind regards,
David.
