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))

A problem with run-mode-hooks was fixed on the release branch a some
days ago -- would it be possible for you to check the emacs-28 branch
and see whether it fixes this problem, too?

My method of building is in a docker container from a .tar.xz file.
Can you tell me how to generate that from the emacs-28 branch?  I will
be happy to test it tomorrow.

Thanks.

I don't know how to create a .tar.xz snapshot, but I know how to
create a .tar.gz snapshot.  Point your Web browser at

  https://git.savannah.gnu.org/gitweb/?p=emacs.git;a=shortlog;h=refs/heads/emacs-28

then click on the "snapshot" link of the latest commit you see there.
The browser will then download a .tar.gz tarball that gives you the
Git repository state at that commit.

You can download a .tar.gz tarball of the emacs-28 branch like this:

  wget https://git.savannah.gnu.org/cgit/emacs.git/snapshot/emacs-28.tar.gz

Alternatively, point your Web browser at

  https://git.savannah.gnu.org/gitweb/?p=emacs.git;a=shortlog;h=refs/heads/emacs-28

then click on the "snapshot" link of the latest commit you see there.
The browser will then download a .tar.gz tarball that gives you the
Git repository state at that commit.

Sorry, don't know anything about docker.

But I've now tested your test case, and I can reproduce the problem in
Emacs 28.1 (we enter an infinite loop), but not on the emacs-28 branch,
so this has been fixed for Emacs 28.2.

No worries, seems moot now.  Also, now I know how to download a tar.gz
of a branch HEAD.

Thanks.

I want to point out that this is a workaround for 28.1, replacing the
defun for common-lisp-mode with this:

(defalias 'common-lisp-mode 'fi:common-lisp-mode)

That seems like the better way to do it anyway.

Thanks everyone.
