Subject: 28.2; Crash on MacOS/M1 with treesitter enabled
Date: Sat, 15 Apr 2023 15:17:19 -0400

Start with 'emacs -Q' on MacOS with an M1 chip.  I specifically used the
prebuilt binaries from https://emacsformacosx.com/builds.  I could
reproduce this with the latest stable release, as well as with
Emacs-pretest-29.0.90-universal and a nightly with version 30.0.50.

Load the following elisp code:

   (require 'package)
   (add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/") t)
   (package-refresh-contents)
   (package-initialize)
   (package-install 'tree-sitter)
   (global-tree-sitter-mode)

Then press 'Control-Command-D' and Emacs will crash with the following
in the terminal:

   $ ./Downloads/Emacs-30.0.50.app/Contents/MacOS/Emacs -Q
   Fatal error 5: Trace/breakpoint trap
   Abort trap: 6

I tried to run Emacs under lldb to get a backtrace but it seems that
requires disabling system integrity protection and when I did that,
the error no longer occurred.

There is quite a bit of info in the MacOS bug report log but I'm not
sure if that is helpful or not. If so, I'll be happy to provide it.

Regards,
Drew Moseley
