Closes #96395
This repeats "fixed" and "ICE", see rust-lang/glacier#1243 (comment)
I think it's good to add a test before regressing again.

I will approve this, but also I hope this test isn't as flaky as it is in glacier.

@bors r-

I want to look into the ICE. If it really is this flaky, having it in CI will only frustrate people, not actually make sure it doesn't regress again

I opened #96965 which should fix both the ICE and the flakiness

Great! Do you want to keep this open for a while to see that PR fixes the issue actually?
EDIT: I should've read OP carefully, found this:

If this PR solves the flakiness on glacier, we can then merge #96950

I'm going to mark this blocked until we can say "it's okay".

Gracefully handle normalization failures in the prospective inliner cycle detector

Preliminary work for adding the regression test in rust-lang#96950 to our test suite (it was flaky on glacier).

If this PR solves the flakiness on glacier, we can then merge rust-lang#96950

It has been a fair while since #96965 and each nightly since then no longer ICEs, I think it did the trick 👍

Thanks for confirming it! Moving back to waiting-on-review then.
