Segfaults are usually caused by buggy tree-sitter scanners (which are written in C/C++). Can you narrow down which file is causing this?

[santhosh-tekuri]

here are the steps:

git clone https://github.com/santhosh-tekuri/jsonschema.git
cd jsonschema
hx draft.go
press o

this seems to be happening with .go and .md and .rs files.

I noticed one thing. If I delete .git folder then i am able to edit files without any issue.

looks like .git folder presence is causing the segfault

the issue might be something with rendering git gutter

I tried following steps:

• go to somewhere middle of first line and press I' and `
• it gives following backtrace

yeanh that is a known issue that is fixed on master for a long time (#7227). Its caused by compiling with a newer rust compiler. The issue is not present in the official release binary or master. This is an issue with the homebrew package

[santhosh-tekuri]

@pascalkuthe

Thanks. I used the one from GitHub Releases and it works great

This issue shares a common characteristic with other issues. It's another example why the infrequent release schedule isn't a good idea. Users on the official release run into bugs months after they have been fixed because the project doesn't release (here: last released in May, fixed June, bug as of October). Unfortunately, the maintainers seem unwilling to fix their release process to release more frequently. #6362
