I seems that atomic-change-group has problems in case its used while in
the middle of an undo sequence.
Have this function defined:
(defun undo-bug ()
(interactive)
(catch 'done
(atomic-change-group
(insert "a b c")
(throw 'done nil))))
$ emacs -Q
C-x b xxx RET
xxx
C-/
M-x undo-bug RET
Debugger entered--Lisp error: (error "Undoing to some unrelated state")
signal(error ("Undoing to some unrelated state"))
error("Undoing to some unrelated state")
cancel-change-group(((#<buffer xxx> nil)))
...
