--- Comment #12 from Richard Guenther <rguenth at gcc dot gnu.org> 2012-06-01 11:50:33 UTC --- You bootstrap-lto with -march=native -ftree-vectorize and then the bootstrapped compiler ICEs with the posted testcases? That would mean GCC is miscompiled, likely with a vectorizer bug ... that it needs LTO will make it quite hard to track down though :(
