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.
