Well, so far I've tracked the problem down to enabling the graphite useflag while emerging >=gcc-4.4.x. Disabling the graphite useflag returns the cpu usage to normal while emerging gcc. Could I ask some kind geek to try enabling the graphite useflag and then to begin emerging gcc, please? You don't need to sit through the whole emerge -- five minute is more than enough to confirm this bug if you see it too. Just run top while emerging gcc and see who uses most cpu (after the sources are bunzipped and the configure scripts have started running.) Many thanks.
