std::map<char*, GhRecord*>::iterator funcIter = g_oRecordFunctionMap.begin(); while (funcIter != g_oFunctionMap.end()) { GhRecord* pFuncRecord = funcIter->second; funcIter++; ... }
出错的位置都是funcIter++处．有两种情形：
卡死．
崩溃．错误也是很奇怪：
#0 0x00007fcf790ff458 in std::less<char*>::operator() ( this=0x7fcf79302420 <g_oRecordFunctionMap>, __x=@0xf8: <error reading variable>, __y=@0x7fcf45199060: 0x7fcf28042400 "tcpclient.c-tcpclient_recv-71") at /usr/include/c++/5/bits/stl_function.h:387 387 { return __x < __y; } 或者 _Rb_tree_increment(std::_Rb_tree_node_base const*) () from /usr/lib
难道吾使用方式不对？吾反复核查，都没有发现问题．
后来输出funcIter->first，发现是乱码．嗯？于是把KEY改成malloc()的，不再出错了．
当然，改用std:;string应该也可以．
