[Bug fortran/25785] New: gfortran - incorrectly issues an error on tests for optional arguments

["dir at lanl dot gov" <gcc-bugzilla at gcc dot gnu dot org>]

gfortran has started erroring on some "present" statements (Absoft and others
have no problem with this program and older version of gfortran were also happy
with it) -


[dranta:~/tests/gfortran-D] dir% f90 -c present01.f90
[dranta:~/tests/gfortran-D] dir% gfortran -c present01.f90
 In file present01.f90:3

        if (present(data_c1)) then
                   1
Error: The upper bound in the last dimension must appear in the reference to
the assumed size array 'data_c1' at (1).
[dranta:~/tests/gfortran-D] dir% cat present01.f90
      subroutine my_sio_file_write_common(data_c1)
        character,   intent(in), optional :: data_c1(*)
        if (present(data_c1)) then
        endif
      end subroutine my_sio_file_write_common
