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).
