current arch, also happens on the github Ubuntu CI workers.

I think this would be due to #988?

We're seeing the same issue: https://github.com/mozilla/neqo/actions/runs/10844489766/job/30095214032#step:3:103

I think this would be due to #988?

I don't think so, this started happening only recently on my CI. By pinning an older nightly version, this seems to be fixed.

Okay, can someone describe a reproduction scenario?

Okay, can someone describe a reproduction scenario?

This "works" for me:

• start a docker container with docker run -ti --rm ubuntu
• inside docker container, run these commands:

$ apt-get update
$ apt-get install curl
$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
$ . "$HOME/.cargo/env"
$ rustup toolchain install nightly
$ rustup +nightly component add llvm-tools

Okay, great, thanks! I think this is an issue with the upstream toolchains. I opened a Zulip topic and am now looking at recent rust-lang/rust PRs to see if something there is relevant here.

Our github runners (Ubuntu 22.04.4) are now experiencing this exact same issue with the latest nightly. Yesterday's version was fine.

Okay, looks like this is getting fixed here:

• Revert #130040 - unify llvm-bitcode-linker, wasm-component-ld and llvm-tools logics rust#130292

rust-lang/rust bug is here:

• Component conflict with bin/llc rust#130291

Thanks a bunch!
