结构值在c++中不能正确打印

我有一个字符串消息，我正在分割字符串并将其存储在一个结构中。

 struct logMessage
 {
   int cefVersion;
   char *deviceVendor;
   char *deviceProduct;
   char *deviceVersion;
   int signatureID;
   char *eventName;
   int severity;
   char *objectIp;
   char *cs2;
   char *suser;
   int logonID;
   char *logonType;
}; 

我已经将字符串拆分并将其存储在我的代码结构中，就像这样。

'split(string str)
{       
            string logmsg=str;
    logMessage lmsg;
    string delimiter = "|";
    size_t pos = 0;
    string token;
    int tokens=1;
    while ((pos = logmsg.find(delimiter)) != string::npos) {
            token = logmsg.substr(0, pos);
            cout <<"n"<< token <<endl;
            logmsg.erase(0, pos + delimiter.length());
        switch(tokens){
                case 1:lmsg.cefVersion=atol((char *)token.c_str());
                   cout<<"t token="<<token.c_str();
                   break;
                case 2:lmsg.deviceVendor=(char *)token.c_str();
                   cout<<"t token="<<token.c_str()<<"tlmsg.deviceVendor="<<lmsg.deviceVendor;
                   cout<<"nmessage stored in the sturcture=deviceVendor:"<<lmsg.deviceVendor;
                   break;
                case 3:lmsg.deviceProduct=(char *)token.c_str();
                   cout<<"nmessage stored in the sturcture=deviceProduct:"<<lmsg.deviceProduct;
                   cout<<"t token="<<token.c_str()<<"tlmsg.deviceProduct="<<lmsg.deviceProduct;break;
                case 4:lmsg.deviceVersion=(char *)token.c_str();
                   cout<<"t token="<<token.c_str();break;
                case 5:lmsg.signatureID=atol((char *)token.c_str());
                   cout<<"t token="<<token.c_str();break;
                case 6:lmsg.eventName=(char *)token.c_str();
                   cout<<"t token="<<token.c_str();break;
                case 7:lmsg.severity=atol((char *)token.c_str());
                   cout<<"t token="<<token.c_str();break;
                }   
        tokens++;
        cout<<"ntokens="<<tokens;
        //#cout<<"nmessage stored in the sturcture=deviceProduct:"<<lmsg.deviceProduct;    
    }   
    //#cout<<"nmessage stored in the sturcture=cefVersion:"<<lmsg.cefVersion;
    //#cout<<"nmessage stored in the sturcture=deviceProduct:"<<lmsg.deviceProduct;

    //#cout<<"nmessage stored in the sturcture=signatureID:"<<lmsg.signatureID;
    //cout<<"nmessage stored in the sturcture=eventName:"<<lmsg.eventName;
    //cout<<"nmessage stored in the sturcture=severity:"<<lmsg.severity;
    logmsg=str;
             std::cout << logmsg << std::endl;
}'

在上面的代码中，注释的#行不能正常工作，它正在打印一些其他的值。除此之外，一切都很好，我不明白为什么会发生。
