Save the following in some file foo.el:
#+BEGIN_SRC emacs-lisp
(defun bug ()
(interactive)
(catch 'done
(atomic-change-group
(insert "bug")
(throw 'done nil))))
(setq debug-on-error t)
(switch-to-buffer (get-buffer-create "*bug*"))
(setq unread-command-events
(list
;; insert abc
?a ?b ?c
;; undo once
?\C-/
;; call bug
?\M-x ?b ?u ?g ?\C-j))
#+END_SRC
, then start Emacs like this:
$ emacs -Q -l foo.el
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 *bug*> nil)))

This seems to be a candidate to merge with 26287 and 34405,
the latter two being already merged.
All three bugs have similar Lisp code
(catch ... (atomic-change-group ... (throw ...)))
producing an "unrelated state" error after undo.
Best wishes,
Gábor

Yup; I've merged the bugs now.
