Our web server is currently running IIS 4.0 and we've been setting up a teacher web site database with php 4.0 and mysql. Recently I upgraded our server from PHP Version 4.0b4pl1 to PHP Version 4.0RC2.  To do this, I overwrote the files in my php directory (d:\php), including php4isapi.dll and restarted our web server.  Everything looked fine until I passed session_start(); to the server.  

At first a page calling session_start(); would hang, then if I hit reload on my browser, I received the error "Fatal error: Cannot redeclare class db_sql in db_mysql.inc on line 12"

At first I though this was an error on my part so I looked around the config files, checked file permissions, and eventually was looking for help in #php on efnet.  Nobody seemed to see the problem before (I couldn't find anyone using IIS and Sessions at the same time) so I then thought maybe there was a bug somewhere.

I found the original installation archive I used to install php, and just overwrote the files again in d:\php, and viola!, sessions were working again.  I have a current copy of my phpinfo at http://www.superior.k12.wi.us/login/info.php.  Previously when I had v4.0RC2 installed, the info script still ran fine.

If possible, could I be sent an email on whether this was a real bug, this project is important to our school district and I'd like to be able to upgrade to the newest RC or official release as soon as possible.
