Getting these CI errors in latest nightly:

Thanks for the report! This is fixed on main in #143. I'll publish a new rustix release soon, and then a Wasmtime PR to update to it. After that, it'll be in the following Wasmtime release.

Thank you for quick reaction!

Does this qualify for a patch release in wasmtime?

[sunfishcode]

I don't think so, since it isn't a security problem, and it only affects the very latest Rust nightlies. A workaround is to temporarily pin to a Rust nightly version from a few days ago; I'd be happy to help you set this up if that would help. Also, as an update to the above, I've now made the PR to update Wasmtime, and it has now landed, so it'll be in the next regular Wasmtime release.

[nazar-pc]

I have already pinned Rust nightly of course, but as many projects use latest nightly in CI, this issue is quite annoying and next wasmtime release will only be in a month, so I was hoping patch release can be issued sooner.

[sunfishcode]

I recognize it's inconvenient. I volunteer to do the work to set up the workaround for any project which encounters this; just let me know in a message here.

For anyone following along at home, you need nightly-2021-12-15 or older
