--- Comment #7 from kapinos at itc dot rwth-aachen.de --- Sorry, for not adding the reproducer again. It is very K.I.S.S.: - make (or reuse) an dir w/o read permissions - use it as include dir at *any* Fortran source including empty ones. The output of gfortran 10.2.0 was added previously, cf. > f951: Warning: Include directory ‘./foo/bar’: Permission denied > f951: internal compiler error: in cpp_diagnostic_at, at libcpp/errors.c:41 ....... $ cat runme007.sh mkdir -p foo/bar chmod 000 foo echo "-------------------------------------------------------------------------" gfortran -c -I./foo/bar mini.F90 echo "------------------------------------------------------------------------" gfortran -v $ cat mini.F90 program mini end On 10/6/21 11:23 PM, burnus at gcc dot gnu.org wrote: > https://gcc.gnu.org/bugzilla/show_bug.cgi?id=56659 > > --- Comment #6 from Tobias Burnus <burnus at gcc dot gnu.org> --- > (In reply to Paul from comment #5) >> Just tried all versions of gfortran available up to 10.2.0: the very same >> 'internal compiler error' is still reported using the initial reproducer. > > Can you share the initial reproducer?
