[freetds] Empty string in varcharmax column in ODBC mode

I think I have stumbled upon a bug in the ODBC implementation of
FreeTDS.

 

If you run the following query in ODBC mode against a SQL SERVER 2005,
the query fails to finish.

 

Select ISNULL(D.Description,'') AS Description from some_table

 

If the column D.Description is a varcharmax, the query does not finish.
Here's the kicker, it only fails about 50% of the time.

 

Note: this works fine in db-lib mode.

 

Thanks.
