On a fresh Pi vm (as in svn updated yesterday)
16rFFFF bitOr:(16rFFFF bitShift: 16) ->  -1
On a slightly older Mac vm
16rFFFF bitOr:(16rFFFF bitShift: 16) ->  4294967295, aka 16rFFFFFFFF

This breaks, amongst other things, Color>bitPatternForDepth:, whcih pretty much trashes an image since that gets used to makes cursor bitmaps as you move the pointer around. Nicely fills your window with notifiers…

So come along; hands up the boy that did that! I’ll keep you all in late unless someone confesses. It’s only your own time you’re wasting! Was it *you* Molesworth?
