Interesting: nice work deducing that. This is clearly a bug -- certainly if rpc.yppasswdd dies with a SEGV, which should never happen. Please do report this problem via send-pr(1). However, I think there must be something different about your systems, as bash(1) is a popular shell and if this was a general problem I should think someone would have complained about it by now. Does this apply to other shells than bash -- eg zsh(1), ksh(1)? Does using the '-v' (verbose logging) flag on rpc.yppasswdd get you any more information? Does this still apply if there's an entry for bash in /etc/shells on the NIS server?
