I build new system from /usr/portage/scripts/bootstrap.sh

I get error:

Please post your `emerge --info' output in a comment.

In make.conf been -j5 on 2 core cpu, I change it to -j3 and gcc-4.9.2 compiled fine.
Thanks for the advice.

I know its customary to resolve dups in terms of the older bug, but #545356 has more info.  I don't think this bug is solved.
