If I understand you correctly, the stored procedure runs but the output
parameter is not being bound back to the host variable? This will take
some time to track down (quite a few components involved). What protocol
version are you using?

If OpenClient works for you then by all means use it, it is a well put
together product.  FreeTDS does several things openclient does not (TDS7,
ODBC, wider platform support, pooling if I ever get time to finish it) and
of course there's the whole free software thing, but I'm just one guy
doing this in my spare time, so it is likely OpenClient will always be a
bit more polished and probably has fewer bugs to boot.

John Dumas did some checks for memory leaks just prior to 0.52 and they
were patched.  I'm not aware of any outstanding leaks.
