I have a few customers who prefer zsh to bash. zsh was working fine until a few days ago. Now, all of a sudden, zsh coredumps on login. The filedate / version on zsh has not changed, so I know cpup did not update it. The funny thing is, if I use chsh to make the users' login shell bash, they can log in and then launch a zsh shell from there -- that works fine. But if zsh is the login shell, they see the error below and are disconnected. Anyone seeing similar behavior? Have any clues what might have changed to cause this?
