I'm using FreeTDS 0.64
I'm using the 7.0 protocol.  Note:  I've tried many times to use the 8.0
protocol, but it causes character problems.

No core dump or error, just a hang.

Description is a varchar(MAX) field that is nullable.

Sorry, not varcharmax.  I meant varchar(MAX).

Description is a varchar field? Is it nullable?

What's varcharmax?
