    大家好，我遇到一个比较棘手的问题，c++开发的游戏，如果一步一步点击运行没有问题，但快速不停点击时，在520机型上会随机崩溃；请有经验的前辈给予指引，谢谢。

    可追踪到的游戏内代码是主循环内的

    CoreWindow::GetForCurrentThread()->Dispatcher->ProcessEvents(CoreProcessEventsOption::ProcessAllIfPresent);

    堆栈信息：

    没有这方面的经验，帮忙顶一下。

    另外在Google上搜搜看这个错误吧，应该会有些有用的信息。

    你好 _navy_

    可否尝试更改一下ProcessEvents的参数，目前的CoreProcessEventsOption::ProcessAllIfPresent看样子是让所有的事件都在某个队列里面等待（貌似这个参数是在做DX开发时候才用到的），个人猜测有可能本身机子处理的慢，等待的多了就造成程序崩溃？试试看能不能把值改成其他几个： http://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.core.coreprocesseventsoption

    或者尝试一下这个办法:

    #include <agile.h>

Platform::Agile<CoreWindow> m_window;

m_window->Dispatcher->ProcessEvents(CoreProcessEventsOption::ProcessAllIfPresent);

    不过你提供的堆栈信息似乎没有提到什么特别的信息。
