bottled emacs exit with SIGSEGV when use built-in rust-ts-mode about homebrew-core HOT 6 CLOSED

I think this should be fixed now by

brew update && brew upgrade emacs

from homebrew-core.

But use brew install --build-from-source emacs will not trigger the segmentation fault, maybe the new version of tree-sitter package broke the treesit support of emacs built with an older version of tree-sitter?

Yep,
tree-sitter/tree-sitter#3296

from homebrew-core.

If there's a command-line/scriptable way to trigger the crash, we can add it to the emacs test block to avoid breakage like this in the future.

I'm not an emacs user, so suggestions welcome.

In the meantime, the rebuild I triggered in #172484 will fix this.

It may be a bit difficult to reproduce the crash through a command-line or scriptable method. Tree-sitter can be used by many emacs major modes, but there is no generic way to test tree-sitter support.

The script below is just an example:

echo "(add-hook 'emacs-startup-hook 'rust-ts-mode)" >> ~/.emacs.d/init.el
emacs

I do not think this is a reliable way to trigger the crash.

Sorry, I forgot to mention a crucial point: we need to first install the corresponding language grammar in Emacs, which appears to require an interactive process.
