Qt程序运行时出现Error - RtlWerpReportException failed with status code :-1073741823. Will try to launch the process directly原因总结

####### Qt程序在运行时出现了上述错误,并且我的程序出现了数据错乱的情况,百度后说是因为内存原因,段错误,仔细查看了自己的代码并没有发现 指针变量未初始化的情况。
####### 通过调试得出原因:QNetworkManager类,在使用时,可能在同一时间段内QNetworkRequestattribute被两个对象同时设定和使用,导致出现数据错乱,数据无法正常取出的情况!
####### 解决办法: 重新建立QNetworkManager分别针对不同的对象,这样它们attribute的使用区域不会重叠
我编写这个函数的部分代码如下:

   // 请求开始
void Request::get(void *attribute, QUrl url)
{
    QNetworkRequest request(url);
    request.setAttribute(QNetworkRequest::Attribute(QNetworkRequest::User + 1), QVariant::fromValue(attribute));
    this->get(request);
}
    // 请求完成
    QVariant attribute = request.attribute(QNetworkRequest::Attribute(QNetworkRequest::User + 1));
    if(attribute.isNull())
    {
        emit dataRequested(receivedData);
    }
    else
    {
        void * attributePointer = attribute.value<void *>();
        emit dataRequested(attributePointer, receivedData);
    }
 // 出错位置 
    // attribute首先在这里被占用
    void *widgetAttribute = (void *)homeMovieItem;
    this->homeImgRequest->get(widgetAttribute, QUrl(homeItem->imgPath));
    connect(this->imgRequest, SIGNAL(dataRequested(void*,QByteArray)), this, SLOT(onReceivedItemImg(void*,QByteArray)));
    // 这里attribute再次被占用
    void *widgetAttribute = (void *)actressWidgetItem;
    this->actressImgRequest->get(widgetAttribute, QUrl(actressItem->imgPath));
    connect(this->imgRequest, SIGNAL(dataRequested(void*,QByteArray)), this, SLOT(onReceivedActressImg(void*,QByteArray)));
