If output_buffering is set to 4096 and session.use_trans_sid is used, the
output may be broken:

<a href="index.php"?PHPSESSID=fa562d5bb14df890e6db68627ea76442>


I've found that the same bug was reported in 2003 for php-4.3.8 (which was
fixed back then) and filed under #29333:
http://bugs.php.net/bug.php?id=29333.
The problem is reproducable with the code that Alan has still on his
website.

I hope it's ok to refer to bug #29333.

Reproduce code:
---------------
As described in #29333

Expected result:
----------------
As described in #29333

Actual result:
--------------
As described in #29333
