Those zeros are a problem, no doubt about it.  

Do the db-lib unit tests t0013.c and t0014.c work with your server?
That would verify that dbwritetext() works with the TDS version you're
using.  

The log doesn't record the value of the textptr returned by dbtxtptr.
If the server is sending a NULL textptr, see if that changes using TDS
7.1.  If not, if you're receiving a good textptr from the server, you
need to find out why you're sending a NULL textptr.
