.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

Sorry if may message very long...

If you try to set the same status code twice, you'll see this leak. I have a patch that I'll apply later today.

I had success changing a line:
//@header("HTTP/1.0 200 OK");

This bug has been fixed in CVS.
