c++ - 使用 boost 序列化获得不可取消引用的 map/set 迭代器的机会是什么

Question

我不断map/set iterator not dereferencable在我的程序中得到一个断言。我完全困惑，因为我很难理解为什么会发生这种情况。在浏览下面给出的堆栈跟踪时。

我怀疑这可能是由于提升序列化引起的。我正在序列化如下：

void DipqCon::Dispatach_Ecl(SomeObject &hf)
{
   std::stringstream ss; 
   boost::archive::text_oarchive oa(ss); 
   oa << hf;
   std::string serialized = ss.str();
   DoSomething(serialized);
}

我想知道在这里获得断言的机会（如果有任何获得 map/set iterator not dereferencable）断言。
