Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

When you do: you already have 'sa' inside a session, registering it again is what causes the problem. It is also recomended that you use $_SESSION autoglobal to initialize session rather then session_register();
