SQSH/FREETDS & MS SQLSERVER 2005 - *** glibc detected *** sqsh: double free or corruption

I have a repeatable issue with freetds/0.82 and sqsh/2.15 on both cygwin(1.5.25) and Kubuntu 7.10. I compiled freetds and sqsh from source code under gcc. When I do "go | less" in sqsh, it just crashes from time to time, and error is always something like:

*** glibc detected *** sqsh: double free or corruption

I did an ldd on sqsh, here is what I get from kubuntu 7.10. 

Any hint or solution for this issue? I have been using sqsh for many years on Sybase under OpenClient, so I guess this is more of a FreeTDS issue? I also thought the issue could be related to uni-code, but I doubt it now.

$ ldd `which sqsh`
