try with saner cflags. suggested "-O2 -pipe -mtune=athlon64 -march=athlon64 -fomit-frame-pointer" Reopen if isn't working with them
OMG I'M FLYING SO FAST OH S***
HOLY COW I'M GOING SO FAST OH F***
The -fmove-all-movables CFLAG seems to cause the troubles. Maybe the ebuild should filter it out.
from the gcc man... -fmove-all-movables -freduce-all-givs These two options are intended to be removed someday, once they have helped determine the efficacy of various approaches to improv- ing loop optimizations. I'm not sure about adding filters for every cflags. I'm all for let people experiment, if they know what are they doing. bug closed since is getting a bit of noise and is solved
