I'm not keen on trying to update to 7.2. Is there a reproduction > that will work on 6.6.4? I am trying to find a case that works without invoking Prolog at all. However, this will definitely take me a while because ediprolog is also involved and the buffer switching etc. that ediprolog does behind the scenes may in fact also contribute to the regression with undo. If you send me your SSH public key, I will create an account for you on a machine where you can reproduce this issue (with emacs -nw). Also for you Eli of course! All the best, Markus
