C++ 如何将OpenGL驱动程序中的分段错误追溯到源代码？

seg故障始终出现在功能OGLDRV中！来自C:\WINDOWS\SYSTEM32\igdogl32.dll的DrvValidateVersion（）。但是，在我的应用程序中触发错误的原因并不完全一致。有时，当用户启动新QML映像元素的动态创建时，它会触发。有时，导航QML ListView时会触发该故障。这让我怀疑内存损坏或竞争条件，但我只是猜测。我不在自己的源代码中创建或管理任何线程，但Qt会自动为应用程序创建许多线程

不幸的是，我在GDB和QtCreator中的调试经验不足，无法收集有用的信息，从而找到导致此错误的源代码的哪一部分。因此，我的首要任务是获得关于我应该采取哪些步骤才能将此错误追溯到我自己的源代码的建议。从GDB回溯中，我可以看到，当SEGFULT发生时，总是有一个线程来自QQuickPixmapReader:：run in qquickpixmapcache.cpp。此函数似乎依次调用QThread:：exec（），该函数返回一个非零返回代码（表示错误）。但我如何才能找出应用程序中导致这些函数失败的特定元素呢？是否可以从OpenGL驱动程序或Qt函数中检索一些错误代码以了解更多信息？从回溯来看，QEventLoop:exec（）似乎是一个异常，但是我如何才能了解更多关于该异常性质的信息呢

使用Qt 5.4.0（使用QtQuick 2.2）。在Windows 8.1、MinGW 32位的Dell Latitude 10平板电脑上开发和运行该应用程序

这是我第一次向StackOverflow发帖，请告诉我是否需要调整帖子或添加其他信息。我很乐意发布源代码，但我不确定我自己的代码的哪一部分是相关的，因为我在segfault后的回溯中找不到对我自己的源代码文件的任何引用。下面是最有趣线程的完整GDB回溯。Segfault发生在线程1，QQuickPixmapCache在线程16中可见
