The first thing to be done is to limit the issue to a single file.  I.e.
which file do you need to compile with gcc-4.8 to generate the issue.

You could also bisect gcc to find the broken commit.  The gcc-git
PKGBUILD in the AUR will bisect quite easily (add #commit=xxxxxx at the
end of the source) if you uncomment the lines after the "XXX" markers.
Building with --nocheck will not take too long to build.
