The unwinding crate compiles on nightlies before e2b52ff (the LLVM 15 upgrade), but now it fails with this:

$ cargo +nightly build --target x86_64-unknown-linux-gnu
   Compiling libc v0.2.132
   Compiling gimli v0.26.2
   Compiling unwinding v0.1.4 (/private/tmp/unwinding)

LLVM ERROR: Broken module found, compilation aborted!
error: could not compile `unwinding`

The error happens both when natively compiling on Arch Linux, and when cross compiling from macOS as shown here.

Upstream issue: llvm/llvm-project#57469

Not sure why this starts with LLVM 15, as the issue itself is not new.
