--- Comment #7 from Vladimir Makarov <vmakarov at gcc dot gnu.org> --- Sorry for inconvenience because of my patch. I reproduced the bug with the reproducer using stage1 gcc although strangely the standard bootstrap works ok for me on i686 debian. I think I know the reason for this bug. I'll fix it today.
