Build Information

Build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1458940
Build error leg or test failing: iossimulator-arm64 Release AllSubsets_CoreCLR - System.Runtime.ReflectionInvokeEmit.Tests / System.Runtime.ReflectionInvokeInterpreted.Tests

Error Details

System.Reflection.Tests.InvokeWithRefLikeArgs.MethodTakesRefToRefStructAsArg_ThrowsNSE fails on iossimulator-arm64 (CoreCLR) in both the Emit and Interpreted reflection invoke test assemblies. The test expects NotSupportedException when passing a ref-to-ref-struct argument but receives IndexOutOfRangeException instead.

Assert.Throws() Failure: Exception type was not an exact match
Expected: typeof(System.NotSupportedException)
Actual:   typeof(System.IndexOutOfRangeException)
---- System.IndexOutOfRangeException : Index was outside the bounds of the array.
