Don't ICE during RPITIT refinement checking for resolution errors after normalization #126670 shows a case where resolution errors after normalization can happen during RPITIT refinement checking. Our tests didn't reach this path before, and we explicitly ICEd until we had a test. We can now delay a bug since we're sure it is reachable and have the test from the isue. The comment I added likely still needs more expert wordsmithing. r? ``@compiler-errors`` who's making me work during vacation (j/k). Fixes #126670 |
