Looks like that fixed the problem.  Initial tests are good.

Thanks a lot,

Bill

For Windows:

This might be fixed now.

On a development system that is exhibits this problem we tried pulling
out our customer handler routines and used the vanilla session support
in PHP.  The problem persists.

We very carefully went through our code and made sure that we never
used a variable before we registered it and the specific problem that I
reported does not occur.  But we are seeing, very intermitently,
similiar failures that we cannot explain.  Basically we see a session
"lose" its variables.  This is happening about 10 times in 1000
accesses.  We have not been able to reproduce the problem on demand. 
This is causing us too much pain at this point and we will likely fall
back to 4.2.3 where we do not see the problem.

I really think that the variable register/use that I reported is
exercising a more fundamental problem.  We will try removing our
session handler and see if the problem persists.

Well, a cleaned up php.ini did not seem to change anything.  What I did
was to start from php.ini-recommended and then add local changes.
