调试结果：
while (_Pnext) {//出现读取访问权限冲突
const auto _Pnextptr = static_cast<const_iterator&>(**_Pnext)._Ptr;
if (_Pnextptr == _Myhead || (_Ptr != nullptr && _Pnextptr != _Ptr)) {
_Pnext = &(_Pnext)->_Mynextiter;
} else { // orphan the iterator
(*_Pnext)->_Myproxy = nullptr;
_Pnext = (_Pnext)->_Mynextiter;
}
}
