You should never see this ICE on nightly, because I turned it into a slightly more helpful error instead: #120865

I can't reproduce this ICE by following your directions. Are you sure you can reproduce it with a fresh clone? Are you using something like sccache? I think this arises from something getting jumbled in the target directory, almost certainly running cargo clean will clear out the errant state locally, but if the errant state came from an external caching system, it might be a bit harder to evict it.

You are right that cleaning my workspace caused the issue to no longer reproduce. I am not knowingly using anything such as sccache (I've not heard of it). One possibility is I do run in a devcontainer and it is possible that there were writes from the container host and within container itself that could corrupt some cache.

I'm glad to see that there is a more helpful error. Because I cannot reproduce the issue, I will thus close this.
