Here is a slightly reduced test case:


module m
  implicit none

  type component
  contains
    procedure :: assign
    generic :: assignment(=)=>assign
  end type

  type t
    type(component) :: foo
  end type

contains

  subroutine assign(lhs,rhs)
    class(component), intent(out) :: lhs
    class(component), intent(in) :: rhs
    print *,'defined assignment called'
  end subroutine

end module 

program main
  use m
  implicit none
  type(t) :: infant, newchild
  infant = newchild
end
