@dotnet/jit-contrib can anyone here help us investigate this issue?

The ConsoleKeyInfo has not been change for months.

This JIT test leg seems to be running once a week. This console test passes 47 times, and fails once, on Windows 10 amd64, with CoreCLR x86. https://dev.azure.com/dnceng/public/_test/analytics?definitionId=668&contextType=build

The test is comparing ConsoleKeyInfo instances. The .Equals() methods pass, but the == comparison fails.

Test log: https://helixre8s23ayyeko0k025g8.blob.core.windows.net/dotnet-runtime-refs-heads-main-5a8e57a8f2b14ffe9b/System.Console.Tests/1/console.dd29db9d.log?sv=2019-07-07&se=2021-10-30T09%3A32%3A44Z&sr=c&sp=rl&sig=CwCNOuPBFlwnNhP8FR4dwL0nJ7DVi5MHgRJFaJnOJTs%3D

Here's the code that fails:

runtime/src/libraries/System.Console/tests/ConsoleKeyInfoTests.cs

Lines 40 to 42 in 57bfe47

	Assert.True(cki.Equals((object)other));
	Assert.True(cki.Equals(other));
	Assert.True(cki == other);

ConsoleKeyInfo is a readonly struct:

runtime/src/libraries/System.Console/src/System/ConsoleKeyInfo.cs

Line 8 in 57bfe47

public readonly struct ConsoleKeyInfo : IEquatable<ConsoleKeyInfo>
