Dear Andre,
Everything works as expected with your new patch.
I have changed the test for pr57305 to
use iso_c_binding
implicit none
integer :: i
real, target :: e
class(*), allocatable, target :: a(:)
do i = 1, 3
e = i
call add_element_poly(a,e)
select type (a)
type is (real)
print *, a
end select
end do
contains
subroutine add_element_poly(a,e)
use iso_c_binding
class(*),allocatable,intent(inout),target :: a(:)
class(*),intent(in),target :: e
class(*),allocatable,target :: tmp(:)
type(c_ptr) :: dummy
interface
function memcpy(dest,src,n) bind(C,name="memcpy") result(res)
import
type(c_ptr) :: res
integer(c_intptr_t),value :: dest
integer(c_intptr_t),value :: src
integer(c_size_t),value :: n
end function
end interface
if (.not.allocated(a)) then
allocate(a(1), source=e)
else
allocate(tmp(size(a)),source=a)
deallocate(a)
allocate(a(size(tmp)+1),mold=e)
dummy = memcpy(loc(a(1)),loc(tmp),sizeof(tmp))
dummy = memcpy(loc(a(size(tmp)+1)),loc(e),sizeof(e))
end if
end subroutine
end
and get the expected outputs at run time (it works also if I replace MOLD with
SOURCE and remove the second ‘dummy = …’ line).
Thanks for your patience,
Dominique
