I guess it doesn't understand CMOV. I can remember trying i686 first and having problems with several applications then... afair /usr/ports/editors/joe was among them (crashed when starting). I had already heard about that CMOV thing then and blamed the crashes on the i686-setting. Since I moved to k6-3, everything is just fine. cu Gerrit --
