我正在尝试使用CUDA（8.0版，GPU GTX980）在GPU上进行一些处理。显示器已连接到此GPU。我的Qt5（5.9.1版）应用程序基本上可以正常运行，但是会随机崩溃。
这是一个非常基本的程序。
到目前为止，我仅使用CUDA进行数据传输，没有内核执行。
一个Qt主循环和一个QThread。 QThread正在运行while循环，它在等待QThread::msleep(1)的信号。
我尝试了使用具有相同结果的QThread的两种不同范例（子类化和moveToThread）。 我仔细分离了代码以维护线程安全（仅在QThread中访问CUDA），并使用信号/插槽进行主循环和QThread之间的通信。
最终，我还可以通过将鼠标移到GUI窗口来使应用程序崩溃。 当我调查GDB时，会看到不同的回溯。下面有两个例子。

由于我经常看到XCB，我怀疑显示设备和CUDA的GPU共享存在问题吗？
有人可以帮忙吗？
我应该显示一些代码吗？
