--- Comment #4 from anlauf at gcc dot gnu.org --- (In reply to Jakub Jelinek from comment #3) > This was added in r11-5064-g0c81ccc3d87098b93b0e6a2dd76815e4d6e78ff0 Right, thanks. There were a couple of regressions introduced by this patch, and these are not yet completely resolved on mainline and on 11-branch. I'd say this is not something that can be easily backported. The best option for the reporter is to upgrade to a newer gcc.
