Fails with

inlinable function call in a function with debug info must have a !dbg location
  call void @_Unwind_Resume(ptr %197) #15
rustc-LLVM ERROR: Broken module found, compilation aborted!
error: could not compile `unwinding` (lib)

Probably a compiler bug.

Does updating unwinding-rs work?

[sunfishcode]

It's already using unwinding v0.2.2, which is the latest version.

[bjorn3]

rust-lang/rust#101121 has an identical error message but was supposedly fixed over a year ago already.

[sunfishcode]

With the latest nightly Rust, it now passes on x86-64 and i686, but it still fails on riscv64.

[bjorn3]

I can't reproduce the aarch64 failure locally.

Edit: I can't reproduce it on x86_64 cross compiling to aarch64, but I can reproduce it on aarch64 natively.

[bjorn3]

I was able to reproduce crash independently of c-ward, but only when incr comp is disabled. I opened nbdd0121/unwinding#34 to track it on the unwinding side.

[sunfishcode]

Adding these [profile.dev.package.unwinding] workarounds to all users isn't great, but I think it's the best option for now.
