Eric, 

I said I'd at least *read* your message, and I did that much.  I'm going
to offer a guess and a hope, since 1) I can't test against an MS server
and 2) I'm not perfectly sure what's in what release of FreeTDS.  

AIUI, you bumped into 2 problems:

1.      config->hostname not getting set, leading to a segmentation fault.
2.      Unknown marker error, having hacked around #1.

My guess is that there's some problem in FreeTDS's reading of your
freetds.conf file, leading to the host name not getting set and to the
TDS protocol defaulting to 5.0.  IIRC, freetds.conf was introduced with
0.52, meaning at the very least the file parsing is new code.  

My hope is that you can confirm/disprove my guess by looking at your
dump file with a little guidance from someone, possibly Brian.  I have
to believe it's pretty easy to determine what protocol version is being
used to communicate to the server.  If it's not 7 and freetds.conf (or
interfaces) indicates 7, there's a mismatch to track down.  

Anyway, that might be one way to narrow down the problem.
