Yes, this looks like a bug. I see something went wrong between versions 6.6 and 6.7.
As for `define` vs `define/private`, they are not the same. In the `define` case, storage is allocated in the object (since it is a field, bound to a procedure) and in the `define/private` case, it isn't (since it is a method).
