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
