Yet another good bug (I'm on a roll today! :-) When squeezing update frames, make sure the updatee pointers aren't identical before updating one to point to the other. This is mostly harmless, but in one example I have caused the program to go into an infinite loop rather than fall down a black hole. To be merged into the 4.08 branch.
