我使用Qt5.3.2，mingw，windows7 32位。我的屏幕：我认为我的驱动程序有问题，我尝试删除并设置了Qt，但较旧的版本（Qt 4.8.6）并已运行。是否存在堆栈帧或至少模块崩溃？因为我不能重现那个错误，我不知道。如何找到该模块并修复它？请查看调试窗口中的模块和堆栈帧。通过查看地址（例如，查找两个0x143d1fa6之间的地址）0？？C:\Windows\system32\ig4icd32.dll 0x143d1fa6 1？？0xababababab是您的英特尔OpenGL驱动程序，您可以看到它是哪个模块。您能在调用堆栈中看到调用它的内容吗（很可能是GLWidget，但是哪个函数）？
