It seems that something went wrong with Assert.Equal, when comparing two System.Collections.Generic.HashSet'1[System.Int32] objects.

When turning on trace, I got

  info: [0x1:] EXCEPTION handling: System.NullReferenceException: Object reference not set to an instance of an object.
  info: [0x1:] EXCEPTION handling: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
