--- Comment #29 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > How do the remaining failures look like? Part of them are darwin specific and several have already been reported (see https://gcc.gnu.org/bugzilla/buglist.cgi?bug_status=NEW&bug_status=WAITING&bug_status=ASSIGNED&bug_status=UNCONFIRMED&bug_status=REOPENED&email1=dominiq%40lps.ens.fr&emailassigned_to1=1&emailreporter1=1&emailtype1=exact&list_id=201803). Another part is also seen on linux (see https://gcc.gnu.org/ml/gcc-testresults/2018-02/msg01178.html). Digging through ~500 failures is no fun and I'll wait for some fixes for the above. However I have restore my testing of the gfortran test suite with -g -flto and I see the following new failures: FAIL: gfortran.dg/namelist_14.f90 -g -flto (internal compiler error) FAIL: gfortran.dg/namelist_14.f90 -g -flto (test for excess errors) FAIL: gfortran.dg/namelist_69.f90 -g -flto (internal compiler error) FAIL: gfortran.dg/namelist_69.f90 -g -flto (test for excess errors) FAIL: gfortran.dg/namelist_70.f90 -g -flto (internal compiler error) FAIL: gfortran.dg/namelist_70.f90 -g -flto (test for excess errors) all of them of the kind /opt/gcc/_clean/gcc/testsuite/gfortran.dg/namelist_14.f90: In function 'foo': /opt/gcc/_clean/gcc/testsuite/gfortran.dg/namelist_14.f90:96: internal compiler error: in add_dwarf_attr, at dwarf2out.c:4353
