--- Comment #12 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> --- I have a patch testing for this. I am not sure this is a regression. I see it as far back as 4.5. I don't have any earlier builds. My thinking is that since this is an ICE on invalid code, I don't want to bother with backports, unless this is just really burning someone somehow.
