Yeah. Having types own decls causes failure of serialization/deserialization
on this code:

struct s {
};

The struct is serialized twice: once by translation unit, the other by the
type which owns it. When deserialized the second time, RegisterPtr() fails
due to that the backpatch map already has final pointer.
