I should mention that <0> works but <0,1> fails. That might get a hint to a
person fixing the issue of what is going wrong inside the compiler.

Simple workaround is to do:


  if constexpr(I)
  {
r.v_[I] = c + this->v_[I] + (I < M ? o.v_[I] : T{});
c = c ? r.v_[I] <= this->v_[I] : r.v_[I] < this->v_[I];
  }
  else
  {
c = (r.v_[I] = this->v_[I] + o.v_[I]) < this->v_[I];
  }
