--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- If it is Fortran FE, then the possible commits might be r14-9893 r14-9874 r14-9873 r14-9753 r14-9752 r14-9720 r14-9719 r14-9712 Anyway, best would be to try to compile the amg_d_jac_smoother_clone_settings.f90 CU with a different compiler from the rest and see whether that is what changes the testcase, or if not, bisect among *.o files in the package, the *.mod files should be hopefully compatible between the 2 compilers. And when a single CU is known to change the outcome, then bisect it with gcc revisions.
