session_start() --> no more output

Hi, the following PHP script causes me trouble: <?php session_register("bunt"); phpinfo(); ?> This is just a simple example. The problem is that the script produces no output at all when called with the browser. I could use <?php session_start(); echo "test"; ?> instead, but I won't get any output either. Everything works as expected when session_start() or session_register() are not used --- phpinfo() then says: Apache/1.3.22 (Unix) Debian/GNU PHP/4.1.0RC2. Any help would be appreciated; thanks in advance! GH -- This mail is copyrighted material and must not be processed by closed-source software.
