      void
      deallocate(pointer __p, size_type __n)
      {
        erase(__p, sizeof(value_type) * __n);
        std::allocator<value_type>().deallocate(__p, __n);
      }

It originates from the call to erase in throw_allocator.h.  It would
appear that the call to delete arising from the call to erase is the
unexpected one.
