This looks like what I need to use. However, I seem to have trouble  
connecting to the database with your tool. I keep getting an error:

bsqldb.c:170: failed assertion `dbproc != NULL'

And when I comment out that line, I get a bus error. I am launching  
it with the same arguments I launch tsql with:

$ bsqldb -S server -U username -P password

tsql seems to be the only thing I can connect to the server with, but  
a strange thing seems to happen with that. If I try to connect with  
the password as an argument (...-P password...), I cannot connect.  
However, if I try connecting without the argument, then just type the  
password in when it prompts me, it will connect. Anyone know the  
reason for this?
