Ah, interesting. Yes, if you manage to create a memory instance of ObjectFilePECOFF, then there's a very high chance that someone will call GetUUID on it. I strongly doubt that anyone is creating memory instances, or that they even work in the first place, but I suppose we can leave this check just in case.
