Alex, 

Nice bt.  

srclen=4294967295?  Methinks you need "set TEXTSIZE 8000" or so somewhere.
:)  

Some drivers initialize the connection with a size; we let the server do
what it wants.  

One of these days, I'm gonna put a very polite error message in
tds_convert_char that reminds the caller to "set TEXTSIZE to some plausible
number".  Segfaulting without checking is unhelpful. :/

ISTR Brian talking about making TEXTSIZE an item in freetds.conf, but I
don't see it in the docs, so I guess it's not there.  

Cheers,
