PHP 4.0 Bug #9390: PHPSESSID adds itself to $HTTP_POST_VARS

From: aaron.lake@kvaerner.com Operating system: HP-UX 11.00 PHP version: 4.0.4pl1 PHP Bug Type: *Session related Bug description: PHPSESSID adds itself to $HTTP_POST_VARS Problem: For some reason PHP adds PHPSESSID to $HTTP_POST_VARS At login, I use: session_start(): $sid = session_id(); session_register("sid"); etc..... 2 pages into the session the var PHPSESSID appears as the first element in the post array. My app has been been behaving until I started playing with gc_probability in php.ini. My identical dev website with identical code does not reproduce this problem.
