Yes, it will break if Array.prototype is an ordinary object because of the special treatment that Array.prototype.concat gives to arrays. Also, JSON.stringify. An alternative fix would be to make IsArray(Array.prototype) answer true, but that seems like even a big hack. It's also hard to specify in a manner that works cross-realms.
