@kotlarmilos looks like dotnet/runtime#84304 which should be fixed already

kotlarmilos · 2023-05-04T08:31:32Z

Correct, it has been fixed by dotnet/runtime#85048.

There may have been some other changes that caused the regressions.

DrewScoggins · 2023-09-05T17:50:36Z

Some tests are still regressed.

kotlarmilos · 2023-09-08T20:13:00Z

Thanks for the heads up. I will go through your comparison and compare it against dotnet/runtime#77490.
