We're seeing static analyzer use after move warnings on both these cases:

  iplist_impl(iplist_impl &&X)
      : TraitsT(std::move(X)), IntrusiveListT(std::move(X)) {}

  iplist_impl &operator=(iplist_impl &&X) {
    *static_cast<TraitsT *>(this) = std::move(X);
    *static_cast<IntrusiveListT *>(this) = std::move(X);
    return *this;
  }

Duncan - you committed this back at rL281181 - any suggestions?
