QNetworkAccessManager 工作得很好，然后每次在 get() 方法上都开始崩溃，这非常简单：

QNetworkReply *reply = myManager->get(QNetworkRequest(QUrl(myUrl)));

堆栈如下：

PS 现在有时会在这一行开始崩溃：

QList<QNetworkInterface> interfaces = QNetworkInterface::allInterfaces();

其他团队成员当然可以从其他 PC 和其他地方运行此代码而不会出现问题。可能是什么原因？！网络问题，防病毒软件，防火墙（试图关闭两者都没有运气）等？！为什么它调用 QNetworkProxy::setPassword？！我没有代理，试图NoProxy明确设置也没有运气。问题可能是什么？有任何想法吗？
