bug#66637: 29.1; Emacs crashes with activating tree-sitter modes

[Kristjon Ciko <kristjoc@ifi.uio.no>]

It seems like this is a MacOS-specific issue; more precisely, a MacOS Sonoma-specific since I did not have this problem before the upgrade.

I reinstalled Emacs using `sudo port install emacs-app` and I found out that the issue occurs **ONLY** when Emacs (vanilla Emacs, no config files involved) is launched from the Spotlight search, which points to /Applications/MacPorts/Emacs.app.  Everything works just fine if I run emacs from the terminal (`which emacs` => /Applications/MacPorts/Emacs.app/Contents/MacOS/emacs)

Same case with my own config; launching it from terminal seems the way to go.

Cheers

This doesn't crash for me, although I use c-ts-mode all the time.

I'm not on macOS, so either this is macOS-specific, or your personal
copies of the tree-sitter and/or the grammar libraries is faulty.  In
any case, please show the backtrace from the crashes by running Emacs
under a debugger.

Thanks.
