reduced test case:

! by the C_FUNPTR
character, allocatable, save :: my_message(:)
! Interface block for the procedure pointed to
! by the C_FUNPTR
public abstract_fun
abstract interface
function abstract_fun(x)
use ISO_C_BINDING
import my_message
implicit none
integer(C_INT) x(:)
character(size(my_message),C_CHAR) abstract_fun(size(x))
end function abstract_fun
end interface
contains
! Procedure to store the message and get the C_FUNPTR
function gp(message) bind(C,name='BlAh')
! procedure(abstract_fun) make_mess
character(kind=C_CHAR) message(*)
type(C_FUNPTR) gp
integer(C_INT64_T) i
i = 1
do while(message(i) /= C_NULL_CHAR)
i = i+1
end do
my_message = message(int(1,kind(i)):i-1)
gp = get_funloc(make_mess,aux)
! gp = aux(make_mess)
end function gp
! Intermediate procedure to pass the function and get
! back the C_FUNPTR
function get_funloc(x,y)

end function get_funloc
! Procedure to convert the function to C_FUNPTR
function aux(x)
interface
subroutine x() bind(C)
end subroutine x
end interface
type(C_FUNPTR) aux
