$ brew doctor
Your system is ready to brew.

Verification

• My brew doctor output says Your system is ready to brew. and am still able to reproduce my issue.
• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.
• I searched for recent similar issues at https://github.com/Homebrew/homebrew-core/issues?q=is%3Aissue and found no duplicates.

What were you trying to do (and why)?

I tried to use emacs write rust code with emacs built-in treesit rust-ts-mode.

What happened (include all command output)?

Emacs crashed with Fatal error 11: Segmentation fault.

What did you expect to happen?

Emacs works well.

Step-by-step reproduction instructions (by running brew commands)

brew install emacs
emacs

and then input M-x rus to enable rust-ts-mode, it will crash.

[Moroshima]

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?

[Lucartas]

Yep,
tree-sitter/tree-sitter#3296

[carlocab]

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.

[Moroshima]

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.

[Moroshima]

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.

[carlocab]

I think this should be fixed now by

brew update && brew upgrade emacs
