Hi Yuan,I installed tree-sitter version 0.24.4 using brew install tree-sitter. I then tried the following Emacs versions: 1. emacs-plus@30 2. emacs-plus@31 3. Emacs-pretest-30.0.92-universal.dmg(https://emacsformacosx.com/emacs-builds/Emacs-pretest-30.0.92-universal.dmg) 4. Compiled Emacs myself with the following configuration:  ./configure --with-tree-sitter=/opt/homebrew/opt/tree-sitter --with-native-compI attempted to reproduce the issue using the following steps: Move to line 52. Delete all characters following :error-code. Quickly press the spacebar twice. At this point, Emacs freezes. The issue persists across all versions and builds.  ------------Sincerely,Haiyuan Zhang, VinursBinaryBrain LLC 开 2024年11月25日 在 09:48:30, Yuan Fu (casouri@gmail.com) 写到:

Sorry for the late response. I went over the reproduce recipe again, and at least for me, Emacs doesn’t hang anymore. Maybe your Emacs isn’t picking up the right tree-sitter library?
