--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Also tried ../configure --enable-bootstrap --enable-languages=c,c++ --enable-checking=release --disable-multilib --with-tune=generic build, but there it doesn't reproduce in either of stage1 or stage2 (stage3 still building). So most probably LTO bootstrap is the trigger :(.
