I know some people have a cron job that runs emerge to update the system
overnight. If that has emerged the new GCC 3.4 or you have switched it
yourself the system/apps are possibly unstable. Apparently the current
wisdom (explained in links) for rebuilding a proper (clean) toolchain and
world is:

        emerge -e system
        emerge -e system
        emerge -e world
        emerge -e world

If that seems like too much time you have several (officially unsupported)
options:

        emwrap.sh
        emwrap
        tcupdate

thread. First post updated.)

Also buried in that thread is a link to an initial thesis on Linux From
Scratch and toolchain purity which is excellent.

Have fun! ;-)
