Question

我正在使用VS2012。我正在写一个简单的网络游戏。发送/接收功能正常工作。我不明白为什么程序仍然在同一时刻抛出相同的异常 - 当waitForOthers（）函数完成时。我切换了很多断点，看起来程序在这个函数中被破坏之后崩溃了BEFORE在更新乐趣中的waitForOthersMove（）之后。

Expcetion： “StatkiKlient.exe中0x64D1CCC8（msvcp110d.dll）的第一次机会异常：0xC0000005：访问冲突读取位置0x004B6CF4。

如果存在此异常的处理程序，则可以安全地继续该程序。“

vs2012指向的xutility代码：

// MEMBER FUNCTIONS FOR _Container_base12
inline void _Container_base12::_Orphan_all()
{   // orphan all iterators
#if _ITERATOR_DEBUG_LEVEL == 2
if (_Myproxy != 0)
    {   // proxy allocated, drain it
    _Lockit _Lock(_LOCK_DEBUG);

    for (_Iterator_base12 **_Pnext = &_Myproxy->_Myfirstiter;
HERE -> *_Pnext != 0; *_Pnext = (*_Pnext)->_Mynextiter) <- HERE
        (*_Pnext)->_Myproxy = 0;
    _Myproxy->_Myfirstiter = 0;
    }
#endif /* _ITERATOR_DEBUG_LEVEL == 2 */
}

以下是代码：

“的main.cpp”：

#include "Client.h"

Client * client;

void clientLoop();

int main()
{
    client = new Client();

    clientLoop();

    return 0;
}

void clientLoop()
{
    while(true)
    {
        client->update();
    }
}

“Client.cpp”：

#include "Client.h"


Client::Client()
{
    initialized = false;
    me = new Gamer();
    cnet = new ClientNetwork();
}


void Client::update()
{
    if(!initialized)
        waitForStart(); //here crashes



    waitForOthersMove();

 }


    void Client::waitForOthersMove()
    {
            Packet packet;

        char data[2000];

        int iResult = 0;

        std::cout<<"Oczekiwanie na przeciwnikow...\n\n";

    while(true)
    {
        iResult = cnet->receveData(data, sizeof(Packet));

        if(iResult < 0)
            continue;

        packet.deserialize(data);

        if(packet.packet_type = YOUR_MOVE)
        {
            //action
            break;
        }

    }
}



void Client::consoleInit() //only for tests
{
    Gamer set_up;

    Packet packet;

    char data[2000];

    set_up.nickname = "... " + me->id;

    set_up.ships[0].dir = 2;
    set_up.ships[0].size = 2;
    set_up.ships[0].x = 0;
    set_up.ships[0].y = 0;

    set_up.ships[0].dir = 1;
    set_up.ships[0].size = 2;
    set_up.ships[0].x = 10;
    set_up.ships[0].y = 15;

    set_up.ships[0].dir = 2;
    set_up.ships[0].size = 2;
    set_up.ships[0].x = 0;
    set_up.ships[0].y = 0;

    set_up.ships[0].dir = 2;
    set_up.ships[0].size = 2;
    set_up.ships[0].x = 0;
    set_up.ships[0].y = 0;

    set_up.ships[0].dir = 2;
    set_up.ships[0].size = 2;
    set_up.ships[0].x = 0;
    set_up.ships[0].y = 0;

    set_up.ships[0].dir = 2;
    set_up.ships[0].size = 2;
    set_up.ships[0].x = 0;
    set_up.ships[0].y = 0;

    packet.player = set_up;

    packet.serialize(data);

    cnet->sendMessage(data, sizeof(Packet));

}

void Client::gameInit()
{
    Packet packet; 

    char packet_data[2000];

    initialized = true;

    std::cout<<"My id: "<<me->id<<"\n";

    packet.packet_type = GAME_INIT_R;

    packet.serialize(packet_data);

    cnet->sendMessage(packet_data, sizeof(Packet));

    consoleInit();

    std::cout<<"wyslano game_init_r\n";
}



void Client::waitForStart()
{
    Packet packet;

    int messageLength = 0;


    printf("\nPołączono z serwerem. Oczekiwanie na pozostałych graczy...\n");

    cnet->testConnection();

    while(true)
    {

        messageLength = cnet->receveData(dataBuff, sizeof(Packet));

        if(messageLength < 0)
            continue;

        packet.deserialize(dataBuff);

        if(packet.packet_type = GAME_INIT)
        {
            me->id = packet.player.id;
            gameInit();
            printf("Initialized...");
            break;
        }
    }


} - after this parenthesis exception is thorw(i toggled breakpoint here and after this in update function)
