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

Judging from the build log, you might have better success trying with a sane set of CFLAGS, but it's impossible to tell because you didn't say /what/ is using up all that memory.

For what it's worth, you're right: it /is/ due to the "insane" gcc flags.

For reference, I narrowed it down to "-O3" combined with any of "-fgraphite-identity" and "-floop-parallelize-all". I'll add a patch for the ebuild to strip the two -f... flags, but since they seem to be unsupported, I'll close this bug.

Thanks for bearing with me :)
