Here is a reduced version of comment #11:


module type_definitions
  implicit none
  type :: matching 
     integer :: n = -999
  end type
  type, extends(matching) :: ellipse
  end type
end module type_definitions

module elliptical_elements
  implicit none
contains
  function line(e) result(a2n)
    use type_definitions
    type(ellipse), intent(in) :: e
    complex, dimension(e%N) :: a2n   ! <- change "e%N" to "10" 
  end function line
end module

  use type_definitions
  use elliptical_elements
end


Fails for me on x86_64-unknown-linux-gnu with 4.5, 4.6 and 4.7. Apparently
related to type extension.
