Alan, thanks for reporting this problem.  When we update the documentation,
it should indicate that FreeTDS (as of current) configures by default as
threadsafe, which apparently matches unixODBC's arrangement.  We should warn
that threadsafe operation has not been confirmed on FreeBSD.  Prior to
releasing, we should try to get folks here to test multithreading on as many
platforms as possible.  

It's "interesting" that the mixed mode of unixODBC and FreeTDS yielded a
crash.  I would have guessed it would be harmless, at least until you
exercised the re-entrancy.
