Interesting result. I've just attached a much smaller test case to the
ticket - it would be good to see if that fails or passes with RC2, or
breaks at the same point.
The fact that there does seem to be a regression between RC2 and RC3
(either a regression itself, or making a previous bug easier to hit)
makes me think that a release might not be such a great idea.
