            Bug ID: 104585
           Summary: incorrect error for dummy arguments with both VALUE
                    and DIMENSION attributes
           Product: gcc
           Version: og11 (devel/omp/gcc-11)
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: a.shahmoradi at gmail dot com
  Target Milestone: ---

The following interface conforms to Fortran 2008/2018 standards but is not
recognized by gfortran, which seems to still follow the rules of Fortran2003 in
this regard.

```
interface
    function test(Matrix) result(res)
        real, value :: Matrix(:,:) ! valid F2008 (although invalid F2003).
        real :: res
    end function
end interface
end
```

This enhancement requires lifting an existing restriction to allow `value`
attribute with array-like dummy arguments in agreement with F2008/F2018
standards.

Bug 102369 was closed as a duplicate of THIS bug. 

Has this been fixed in a more recent version of gfortran?

No.  We need only one entry for a bug.

Any prediction for this one?   (I realize you still have F2018 an F2023 to get
through.)
