--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> --- The important question is if correct code compiled by gcc 11 was working correctly with libgfortran 11, if yes, then libgfortran 12+ should maintain compatibility (of course, when soname is bumped, that compatibility code can be thrown away).
