Some more details: - this happens for csh but not for bash-1. - ktracing everything shows further strange behaviour. ktrace causes a kernel printf "Out of ktrace request objects.". The login shell is not lost immediately. You get a shell prompt, but at least tty echo is broken, and hitting return a few times causes all the shells to exit. > Is this breakage considered a bug or a feature? Bug.
