OK, try this -- this is all of the data, and I presume that the second (in)
is the response which is failing.

Yes, I did a C++ implementation in a prior life, and it's coming back to me
now.  DNS name compression is funny.

By the way, this is the Windows 2000 DNS server.  I can get you version
information if it's useful.

Thanks for the continued responsiveness.  You're definitely the most
responsive maintainer that I've worked with so far.  Good job!

It's probably not important.  The compression it's doing isn't wrong, it's 
just strange.  I really should rewrite the decompression code at some 
point, but haven't gotten around to it.

Aha, fixed.  For whatever reason, the server is doing name compression in 
a very strange way, and the decompression code wasn't handling it 
properly.  It's fixed in CVS, and I'll make a new release later this week.
