You're essentially suffering from a bug that occurs when gcc
optimization plugins are changing (e.g. upgrade gcc 4.1.x to 4.2.x).
Lunar, right now, is not able to migrate any of your previous choices
to the newer gcc optimization plugin. But since you're using the new
compiler by default you're left without any optimizations at all.

Resetting your optimizations to "normal" values should do the trick.
