我们来看一下源代码是什么原因导致的：
std::string vlog::information()
{
bool is_multiple_th = true;
#if _VLOG_SUPPORT_THREAD_
is_multiple_th=true;
#else //#if _VLOG_SUPPORT_THREAD_
is_multiple_th=false;
#endif //end of #if _VLOG_SUPPORT_THREAD_
//std::cout<<get_level_str(_user_want_level);
//std::cout<<_map_tid_logstr.size();
//_oss.clear(); _oss.str("");
//std::cout<<"user setting log_level:"<<get_level_str(_user_want_level)<<","
// <<"multiple thread mode:"<<is_multiple_th<<","
// <<"map_logstr size:"<<_map_tid_logstr.size()<<std::endl;
}
本以为是多线程的问题，看了半天发现是函数没写返回语句。
