Historically, new gcc releases have landed in rawhide right before a mass rebuild and then there's often been fallout in the mass rebuild due to the new compiler. And then afterwards there's a lot of crunch to get all of the fallout from the new compiler fixed quickly before the Beta release. I think it would be much smoother to introduce new gcc releases earlier in the cycle (as in, now would be a good time) to give packagers time to fix things up before the mass rebuild starts. -- Kalev
