As with #57610, I have been getting a seeming unrelated ICE. I tried rebasing, so hopefully this should be passing now.

It's also worthwhile to note that we had breakage in rustc's own test suite, which I fixed in the last commit...

The 4 fixed appear to be spurious un-failures. There are two regressions:

  • fluid: appears to be spurious
  • nes: is caused by these changes

Since there are regressions, could you turn the error into a future-compatibility lint?
It's not too much work in this case.

@mark-i-m Could you also reach out to the nes crate with a PR perhaps?

Seems like we should be able to turn this into a hard error pretty quickly.
