Bug ID: 99709
Summary: VALUE attribute for an object with nonconstant length
parameter
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: xiao....@compiler-dev.com
Target Milestone: ---
The extensions to VALUE attribute(f2008) permitted for an object with a
nonconstant length parameter, but the result of the following test case
is same with none VALUE attribute.
program value_f2008
implicit none
type :: matrix(k)
integer, len :: k
integer :: elements(k, k)
!integer :: elements(2, 2)
end type matrix
type, extends(matrix) :: child
end type child
type(child(2)) :: obj
obj%elements = reshape([1, 2, 3, 4], shape(obj%elements))
call test_value_attr(2, obj)
print *, obj%elements
contains
subroutine test_value_attr(n, nonconstant_length_object)
integer :: n
type(child(n)), value :: nonconstant_length_object
nonconstant_length_object%elements = 0
end subroutine test_value_attr
end program value_f2008
The result is
0 0 0 0
