Ok, let's test this theory.  If you did something like:

DBINT i;

memcpy(&i, dbdata(dbproc, 2), sizeof(i));

and then use 'i' instead of dbdata() directly does the problem go away?

The information in the row buffer *should* be 4 byte aligned, I remember
at least one alignment patch in the 0.60 series, so it'd be worth a try. 
If not it's definately a bug on our part.

 0xa7939 should be 0xa7938 (34 + 4 = 39?)  maybe a TDS 7.0 thing, have you
tried setting the tds version to 4.2 and tring it?

TDSVER=4.2; export TDSVER

and then run.  If that works it is specific to 7.0 and we'll know where to
look.
