Confirmed on x86_64-apple-darwin10.6.0. Reduced test case:


module gyre_kinds
  implicit none
end module

module gyre_bvp
  type :: bvp_t
  end type
end module

module gyre_jacobian
  type :: jacobian_t
     integer :: n_e
  end type
end module

module gyre_lanr_jacobian
  use gyre_jacobian
  type, extends(jacobian_t) :: lanr_jacobian_t
   contains
     procedure :: eval
  end type
  private
  public :: lanr_jacobian_t
contains
  function eval (this, w) result (A)
    class(lanr_jacobian_t) :: this
    real       :: w,A(this%n_e)
  end function
end module

module gyre_lanr_bvp
  use gyre_lanr_jacobian
end module



This surely is a duplicate of PR47546 (or at least closely related).
