Why is this a bug? In 1.phtml, you've started a session, and registered the two variables $vara and $varb as session data. In 2.phtml, you've set $varb to "No Value", and *then* you've restored all of the session data by calling session_start(). This overwrites $varb with the previous saved value. The following session_register() call is a no-op, because vara is already a registered variable with the session. AFAICT, this is all per the documentation in the PHP manual.
