------- Comment #1 from jv244 at cam dot ac dot uk  2010-05-16 06:57 -------
reduced testcase:

module mod_tetgen
  use iso_c_binding
  type tetgenio
     double precision, pointer :: pointlist(:,:)
     integer :: numberoffacets = 0
  end type tetgenio
contains
  subroutine tetgenf( in, out )
    type(tetgenio), target, intent(in)    :: in
    type(tetgenio), target, intent(inout) :: out
    call tetcall(inhandle, outhandle,     &
         c_loc(in%pointlist), &
         out%numberoffacets)
  end subroutine tetgenf
end module mod_tetgen
