It's trying to connect to the database server and failing. Then the
sql_error function is segfaulting... This looks rather like the Oracle
problem we're seeing just now... Yuck.
Hmm. Go to the sql_error function in sql_iodbc.c and move 'return error;'
from after the SQLError call to before it.
Recompile, restart, and see if it still segfaults.
Then try and work out why it's failling to connect to your SQL server.
(Check your parameters and such... See if there's anything in the server
or iodbc logs that indicates a failure or reason.)
