This is highly likely due to the session handler being called after APC mops up 
the classes.

Can you try adding a session_write_close() at the end of the script?

yes, this works
I have another error, but I do not know whether to the APC module, or if it is related to this solution

PHP Fatal error:  Uncaught exception 'UnexpectedValueException' with message 
'Error at offset 1923 of 38785 bytes' in ....
Stack trace:
#0 [internal function]: ArrayIterator->unserialize('x:i:0;a:10:{i:0...')
....

the error occurs randomly, and I could not detect that is what produces

I can't repro the latter error using apc trunk and php 5.4.9, most likely it's not APC related. Could you test again? Also i've added your test code to tests/bug63224.phpt, would be useful if you'd run it in your environment.
