好像是string的引用计数引起的0x0000005错误，谁来调教一下
在sky_data 读取完成数据以后，
使用printf_tree(ostream&,sky_data*)写入数据的时候会出现这个错误：
根据注释，因该是多线程退出导致的引用计数错误。
但是一直找不到错在哪里。求调教高手来调教一下
printf_tree 源码：
void printf_tree(std::ostream& icout,sky_data* point){ if(point==NULL) icout<<point->_tree_hard.id<<endl; icout<<point->_tree_hard.item_name<<endl; icout<<point->_tree_hard.last_dir<<endl; icout<<"__________________________________________________"<<endl; map<string,item>::iterator iter=point->img_item.begin(); while(iter!=point->img_item.end()) { icout<<iter->second.id<<endl; icout<<iter->second.item_name.c_str()<<endl; icout<<endl; ++iter; } iter=point->doc_item.begin(); while(iter!=point->doc_item.end()) { icout<<iter->second.id<<endl; icout<<iter->second.item_name.c_str()<<endl;; icout<<endl; ++iter; } icout<<"___________________________________________________"<<endl; if(point->tree.empty()) return; map<string,sky_data*>::iterator i_tree=point->tree.begin(); while(i_tree!=point->tree.end()) { printf_tree(icout,i_tree->second); ++i_tree; }}#pragma once#include "stdafx.h"#include<string>#include<vector>#include<map>#include<fstream>#include"_str_.h"unsigned int DIR=0;unsigned int PHOTO=1;unsigned int DOC=2;std::string INDEX="index_dir";struct FLAG{ std::string start; std::string end;};FLAG DIR_FLAG={"<Folder>","</Forlder>"};FLAG DIR_NAME={"<Name>","</Name>"};FLAG PHOTO_FLAG={"<Photo>","</Photo>"};FLAG DOC_FLAG={"<Document>","</Document>"};FLAG ITEM_TYPE={"<ItemType>","</ItemType>"};FLAG RES_ID={"<ResourceID>","</ResourceID>"};FLAG ITEM_NAME={"<RelationshipName>","</RelationshipName>"};FLAG* make_flag(std::string start,std::string end){ FLAG* ret=new FLAG; ret->start=start; ret->end=end; return ret;}struct item{ std::string last_dir; unsigned int flag; std::string id; std::string item_name; bool operator ==(const item&);};item* make_item(unsigned int flag,std::string id,std::string item_name,std::string b_dir){ item* ret=new item; ret->last_dir=b_dir; ret->flag=flag; ret->id=id; ret->item_name=item_name; return ret;}bool item::operator ==(const item& _item){ if(last_dir==_item.last_dir) if(flag==_item.flag) if(id==_item.id) if(item_name==_item.item_name) return true; return false;}class xml_read{public: xml_read(std::string,std::string);private: std::vector<item> Doc_id_name; std::vector<item> Dir_id_name; std::vector<item> Img_id_name; std::string xml_file; item* xml_information;private: void load_xml_hard(std::string,std::string); item read_item(std::string,std::string); bool is_dir_id(std::string); unsigned int what_flag(std::string); public: std::vector<item>& Get_Doc_Id_Name(){return Doc_id_name;} std::vector<item>& Get_Dir_Id_Name(){return Dir_id_name;} std::vector<item>& Get_Img_ID_Name(){return Img_id_name;} void reload_xml(std::string,std::string); item Get_this();};
