我继续在我的程序中获得map/set iterator not dereferencable断言。我很困惑，因为我很难理解为什么会发生这种情况。同时瞥见下面给出的堆栈跟踪。

我怀疑这可能是由于提升序列化造成的。 我按如下顺序排列：
void DipqCon::Dispatach_Ecl(SomeObject &hf)
{
std::stringstream ss;
boost::archive::text_oarchive oa(ss);
oa << hf;
std::string serialized = ss.str();
DoSomething(serialized);
}
我想知道获取（如果有任何获取map / set iterator而不是dereferencable）断言的机会在这里。
