[Bug fortran/32804] New: ISO C Binding: C_LOC argument checking needs improvement

[burnus at gcc dot gnu dot org]

subroutine aaa(in)
      use iso_c_binding
      implicit none
      CHARACTER(KIND=C_CHAR), DIMENSION(*), TARGET  :: in
      type(c_ptr) :: cptr
      cptr = c_loc(in)
      end subroutine

Wrongly rejected with:
  Error: CHARACTER argument 'in' to 'c_loc' at (1) must have a length of 1

      subroutine aaa(in)
      use iso_c_binding
      implicit none
      integer(KIND=C_int), DIMENSION(:), TARGET  :: in
      type(c_ptr) :: cptr
      cptr = c_loc(in)
      end subroutine

Wrongly accepts this; NAG f95 writes:

Error: aa.f90, line 6: The argument to C_LOC must not be an assumed-shape array
