Hmm, I think this is a relatively new thing; it also core dumps for me
on multiple undo-ings.

Oliver's latest patch in 38540 stops the core dump, but it also stops
the undo from happening at all; in fact if I attempt ESC x undo RET
then not only does the undo not happen, but the RET is interpreted as
accept-line instead of as the end of the execute-named-command input.
