--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Can you attach then preprocessed copy.ii, cc1plus command line and copy.s (with additional -dA) from both r241136 and r241137 + http://gcc.gnu.org/ml/gcc-patches/2016-10/msg02062.html ? The test is -std=c++11 and there are no inline variables, so there shouldn't be any between those two.
