Just to clarify: I can see it, but I am not "working on it".

This should be fixed now. Would people please test and let me know if my
fix solved it. If you haven't seen the fix, it was completely in
apr-util, so the CVS commit message went to the apr-cvs list.

Re: Corrupted headers with Apache2.0

The problem is easy to debug, but I haven't had a chance to fix it yet.
We have set the b->length field incorrectly for heap buckets. This is
related to the bucket changes from last night. Basically, the length used
to store how much data is in the bucket for heap buckets, regardless of
how much is allocated. Now, it is how much is allocated + how much is
used.
This is obviously a bug. Fix is imminent, assuming I don't get swamped as
soon as I reach the office.

There's an large chance that this is due to a bug somewhere in the buckets
code I checked in yesterday. I'll review my changes (again)... but the
strange part is that it works for me. It'd help if I had more details
about your platform... MMAP or not? Sendfile or not?

(I recommend netcat (nc) and "cat -v".)
Yes, I can reproduce this with a snapshot of apache-2.0 from three hours
ago. On my server (Apache/2.0.14-dev prefork), I get
1) garbage between the response line "HTTP/1.1 200 OK" and the first MIME header
2) thousands of NIL characters at the beginning of each MIME header line
(made visible by "cat -v" and collapsed from ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@...

Here's the command I enter, and the result I get (server running on port 8007):
