I noticed something similar in Firefox, which from skimming the build
log sets -O3 internally regardless of what the user has set. This is
troubling for two reasons:

1) Gentoo (apparently) has a policy of not allowing packages to mangle
CFLAGS and CXXFLAGS, even with user permission (a useflag of eix was
removed because it set -O3 when enabled).
2) Firefox is the only application I run that crashes, and I don't
know how to disable -O3 to potentially make it more stable.
