cannot seek value-initialized vector iterator 程序崩溃

程序启动了一会 送了一张图

dump是这样的

打开远程调试 终于定位到了问题

//提取错误号并去重
std::transform(alarm_msg_datas.begin(), alarm_msg_datas.end(), req->m_alarm_code_list.begin(), [=](const GRPCBlackBoxAlarmLogQueryResponseClientData& a) {return a.alarm_id; });

 

最终在这得到了答案:

通常，对开始/结束迭代器的操作不会调整容器的大小。

std::transform(v.begin(), v.end(), std::back_inserter(v1), mult);
或者
v1.resize(v.size());

std::transform(v.begin(), v.end(), v1.begion(), mult);
