unused: 'unused' terminated by signal SIGSEGV (Address boundary error)

Hello! When running unused, unused --help, and unused doctor, I get the following error:

With fish:

fish: 'unused' terminated by signal SIGSEGV (Address boundary error)

With zsh:

zsh: segmentation fault  unused

I have unused version 0.2.0 installed via Homebrew (unused-code/formulae) on macOS Big Sur 11.2.3 with an M1 Macbook. ctags were successfully generated with Universal Ctags. Maybe it’s something weird with the M1 architecture?

If there’s anything I can do to help debug, let me know!

@sergiopantoja @jcamblan @marckohlbrugge thanks for your patience while I got this sorted!

I’ve released version 0.2.2 of unused, which includes a feature flag to enable mimalloc. I’ve also updated the Homebrew formula to opt out of mimalloc use. Finally, I’ve gone ahead and updated the README to account for the additional configuration, including the suggestion to uninstall/untap and then try again.

I’m hoping that as mimalloc gets wider adoption, the ARM issues will iron themselves on the Apple M1s and folks can use it (especially considering it’s significantly faster than the default).

@marckohlbrugge Alright! Want to give this a try?

brew untap unused-code/formulae
brew tap unused-code/formulae
brew install unused  --without-mimalloc --HEAD

Once you’re set with this, could you give unused another try?

@marckohlbrugge oh, fascinating! I’ve been running it under /usr/local since I picked up my M1.

It’s still not super clear what the problem would be; a few ideas, if you’re interested (it may require some setup!):

Installing with Rust directly and seeing if that works
Wiping/rebuilding your Homebrew setup (that’s where the Brewfile comes in handy!)
Trying another shell, like bash, to see if there’s something with your current shell that’s somehow mucking with things (I’m not sure why this would cause it, but it’s worth trying maybe?)
