Ran into this while NativeAOT compiling the System.Runtime.Intrinsics.Tests but this has a simple repro with CoreCLR. Not clear why we're not seeing this in test runs.
Compile following:
using System;
using System.Runtime.Intrinsics;
Vector128<UInt128> d = default;
d.GetHashCode();
With csc test.cs /noconfig /nostdlib /r:System.Private.CoreLib.dll /O. Run with corerun.
