I will get this change merged first. This definitely fixes one crash on linux-sparc.
The only reference to that message I can find is from HashMap/HashSet where the load factor defines how full the collection becomes before it resizes. I would have to guess some kind of floating-point issue here - a very small number rather than 0 perhaps?
Then try to track down this issue using hg bisect.
