This is the distillation of a bug that happens in ELI, an emacs-lisp
interface from Franz Inc. It's been around for 30+ years. With 28.1,
visiting files like this (test1.cl in my test case) cause recursion in
run-mode-hooks:
;; -*- mode: common-lisp; package: excl -*-
(in-package :excl)
;; test 1
Start emacs with
emacs -Q -l bug.el test1.cl
where bug.el is:
(defun fi:common-lisp-mode ()
(interactive)
(kill-all-local-variables)
(setq major-mode 'fi:common-lisp-mode)
(setq mode-name "Common Lisp")
(run-mode-hooks))
(defun common-lisp-mode ()
(interactive)
(fi:common-lisp-mode))
