Looks like an llvmlibunwind error. Didn't we have a issue about a fix for that recently? All I can find is https://julialang.slack.com/archives/C688QKS7Q/p1672320601955129 right now

That discussion is #48020 which is waiting for an LLVM bump, but yggdrasil isn't fully back up yet for it. This issue might be different, and maybe a llvmlibunwind bump fixes it. I have a PR started that does it but I haven't done the makefile changes necessary for it just yet.

@anandijain what version of macOS do you have? I couldn't reproduce your issue on macOS 12.6.

Side note, it'd be helpful to make self-consistent bug reports, instead of posts which only contain a link to somewhere else (even if the backreference is still useful).

I can reproduce this on macos13, I tried with a new libunwind but same thing

This is the apple crash handler trace. It does come from deep in apple things so I don't know.

I am suspicious of this

  "usedImages" : [
  {
    "source" : "P",
    "arch" : "arm64e",
    "base" : 7465172992,
    "size" : 45056,
    "uuid" : "1228eddf-7c61-3674-8c42-b537ffe9edda",
    "path" : "\/usr\/lib\/system\/libunwind.dylib",
    "name" : "libunwind.dylib"
  },

I think we might have two libunwinds in the same process, which causes a crash

Is this still an issue?
