@ryansdwilson How did you manage to fix the issue? (I'm assuming you managed to do so given that you've closed the issue relatively quickly). I'm also getting a yjit/target/release/libyjit.a Abort trap: 6 error.

Brew reinstall rust

thanks @ryansdwilson, I've tried that but didn't seem to solve the problem. I'll keep debugging (and may open another ticket if this one cannot be re-opened)

Reopening this since it still seems to be an issue. brew install rust results in LLVM 18 being installed, but Ruby (or Rust?) seem to prefer LLVM 17.

I was able to work around this by explicitly running brew install llvm@17.

Upon further inspection, this looks like it might be a Homebrew bug. The rust Homebrew formula explicitly depends on llvm@17, but brew install rust for me resulted in LLVM 18 being installed but not LLVM 17. According to what I can reconstruct from Homebrew output, Homebrew first installed rust which was satisfied by LLVM 17 already being installed, but then it allowed the upgrade LLVM 17 → 18, and in the end it deleted LLVM 17 as part of its cleanup process (which should not have happened per rust formula dependency).

I am not going to report this to the Homebrew project because I cannot reproduce it anymore, i.e. because the bug depends on a certain state of my system that I am now unable to get back to and therefore unable to explain to the Homebrew team.

Thanks @mislav, explicitly installing llvm@17 worked like a charm.

FYI: rust-lang/cargo#13795 This issue caused by Homebrew's rust/cargo .
