Squeak and Pharo used to have a funky class DirectoryEntry that was expected to be able to be instantiated with DirectoryEntry new: 0. The (Spur) VM bug is that the object was being filled with 0's instead of nil. I've fixed the Spur VM to now fail for any non-indexable class since, AFAICT, DirectoryEntry is no longer used in this way. _,,,^..^,,,_ best, Eliot
