That's exactly the behaviour caused by register_globals being on --
session_start() takes each $_SESSION["var"] and makes the equivalent
global $var be a reference to it. Other variables only get mirrored in
$_SESSION if you session_register() them.

(track_vars, mentioned previously, is a red herring -- it's been
permanently enabled since 4.0.something.)
Cheers!
