From the second more detailed trace, this looks problematic?

Fatal error. 0xC0000005
   at System.Runtime.CompilerServices.CastHelpers.IsInstanceOfInterface(Void*, System.Object)

benaadams · 2020-11-29T20:00:21Z

Failure lines prior/related to IsInstanceOfInterface

runtime/src/libraries/System.Private.CoreLib/src/System/Reflection/IntrospectionExtensions.cs

Lines 13 to 14 in c1b5ac0

    
           if (type is IReflectableType reflectableType) 
        
               return reflectableType.GetTypeInfo();

GrabYourPitchforks · 2020-11-29T20:11:43Z

Steve theorized in the other thread that this might be a crossgen issue. Waiting for that investigation to pan out.

benaadams · 2020-11-29T20:18:24Z

The Xunit Linq usage triggering it is IsSet

bool IsSet(TypeInfo typeInfo)
{
	return typeInfo.ImplementedInterfaces
		.Select(i => i.GetTypeInfo())
		.Where(ti => ti.IsGenericType)
		.Select(ti => ti.GetGenericTypeDefinition())
		.Contains(typeof(ISet<>).GetGenericTypeDefinition());
}

Which then does match the longer Fatal error. 0xC0000005 stack trace (sanitized) /cc @stephentoub

The Xunit Linq usage triggering it is IsSet

Thanks for tracking that down. That explains the call stack I was questioning, but of course not the failure itself.

stephentoub · 2020-11-29T20:39:52Z

Steve theorized in the other thread that this might be a crossgen issue. Waiting for that investigation to pan out.

Looking at Kusto data, this test has failed 50 times, with the earliest failure being at 2020-11-27T15:34:50.565Z, which is very close to the time the crossgen change was merged.

We can try running its tests again, but #45320 reverts #44618 and passed the leg that's failing elsewhere.

Guessing some of these failures are related too; though different callsites and stacks
