Code

Sorry, didn't try to make minimal example. It likely broke in the latest nightly, because yesterday it worked fine in CI.

Error can be reproduced with

• checkout https://github.com/facebookexperimental/starlark-rust/ for example, latest revision b0928b782a94bd1b4237b07c668d33c1805db701
• cargo check -p starlark

I'm pretty sure this is a duplicate of #113941, which was fixed by #113946.

So I'll close this issue as already resolved, but feel free to reopen it if it's not actually fixed in tomorrow's nightly as we'd expect.

Thanks for opening an issue!
