namely this one (which apparently is a regression in 4.9 trunk):

module hilbert_space
  use, intrinsic :: iso_c_binding
  implicit none

  type dSFMT_t
    type(c_ptr) :: dSFMT_state = c_null_ptr
    real(c_double), allocatable :: random_store(:)
  end type

contains

  subroutine dSFMT_init (arg)
    type(dSFMT_t) :: arg
  end subroutine

  subroutine test_rng()
    type(dSFMT_t) :: rng
    call dSFMT_init (rng)
  end subroutine

end module
