This is a known problem. It generally shows itself with older architectures like AMD Phenom II, Bulldozer, Intel Core 2 etc. "-march=native" in the make.conf file was the culprit, IIRC, and replacing it with core2 or amd's equivalent option solved it. I, instead, put "-clang" in my package.use file, for firefox. No problem with Firefox builds since then.
