--- Comment #8 from Richard Biener <rguenth at gcc dot gnu.org> ---
Well, priority to fix this bug is certainly low unless you provide a smaller
testcase than "GCC bootstrap".  Does --without-build-config work?  Or do
you use --with-build-config=bootstrap-O3?

That is, how do you actually compile with -O3?
