I don't think this is a bug, it looks like a misunderstanding of the API.
(Perhaps it is my misunderstanding ;-)
session_is_registered() seems only to test if you have registered a
variable, not if the variable has been retrieved by the session code as of
yet.
session_register() should be called regardless of whether or not you need to
initialize a variable, so what you need to do seems to be this:
session_register("foo");
if(!$HTTP_SESSION_VARS["foo"]) // foo uninitialized
{
$HTTP_SESSION_VARS["foo"]=0; // probably no need to do this, already zero
}
$HTTP_SESSION_VARS["foo"] += 1;
