It builds fine in apple arm, but has some segmentation fault issue when running it.

I too faced this issue on MacBook Pro M1.

Here are commands were added on MacBook for getting core-dump. Here is the stack-trace. Hope this helps you in identifying the issue.

Looks like I can build/test successfully with ventura arm in my local, https://github.com/Homebrew/homebrew-core/pull/153365
