bug#51641: 29.0.50; reproducible crash with org-bullets on yesterday's top of tree on MacOS 12.0.1, Apple M1.

[PAVLOS MARAGAKIS]

Using emacs -q --load load_to_crash_emacs_2021-11-06.el
I load the simple org file load_to_crrash_emacs_2021-11-06.org
and emacs crashes every time with a segfault.

The contents of load_to_crash_emacs_2021-11-06.el are:
;;;;;;;;;;;;;;;;;;;;;
(require 'package)

(setq package-enable-at-startup nil)
(add-to-list 'package-archives
             '("melpa" . "https://melpa.org/packages/";))
(package-initialize)

(unless (package-installed-p 'use-package)
  (package-refresh-contents)
  (package-install 'use-package))

;; Let's also add org packages
(add-to-list 'package-archives '("org" . "https://orgmode.org/elpa/";) t)

(use-package org-bullets
  :ensure t
  :config
  (add-hook 'org-mode-hook (lambda () (org-bullets-mode 1))))
