To be more accurate, when old_resource is disposed of it will dispose of any remaining underlying new_resource objects, leaving a load of invalid new_resource's which will then be free'd later - unsuccessfully. So I either need to preserve the life of the underlying old_resource until all visible new_resources are finished, or find some way to mark the remaining new_resources as invalid. > It seems like there is no destroy order at end-of-page time? > Whats the best way to enforce it? > > I think I am going to have to wrap all the C++ objects in more C++ to > implement reference counting- aggh.
