--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- All of those tests are the same source (3 of them include the fourth), just differ in used options. Could you please sed -i -e 's|abort ()|__builtin_printf ("%d FAIL\\n", __LINE__)|p' c-c++-common/cpp-embed-1.c and retry and see what FAILs?
