For some reason disabling winner-mode solved it when I > last tested it. How strange. Ok. Now I used this: #+begin_src emacs-lisp (defun count-markers-in-buffer-undo-list () "Message number of (different) markers in `buffer-undo-list'." (interactive) (require 'cl-lib) (message "%d" (length (cl-delete-duplicates (seq-filter #'markerp (flatten-tree (copy-tree buffer-undo-list))) :test #'eq)))) #+end_src to get the number of different markers in `buffer-undo-list', after reproducing the recipe. The answer was always "1". Just a bunch of entries referring to one and the same marker. That seems sane. Are you able to provide a more pathological recipe? Regards, Michael.
