Hi James,

I initially run the same test and the results were OK. Then I tried to
specify a different COLSEP and got SEGFAULT, session log follows.

PS: I replaced freetds 0.82 bsqldb.c with the rev 1.39 source and run
configure/make.

Thanks,

Ronildo

Committed TEXT support for bsqldb to CVS HEAD, revision 1.39.  

Thanks for pointing out these problems.  Let me know if the problem is
solved, please.
