因为“未知信号”而在QT创建者中使用dgb进行调试时出错

Question

我正在尝试调试此代码：

#include <stdio.h>
int main()
{
    int firstNumber, secondNumber, sumOfTwoNumbers;

    printf("Enter two integers: ");

    // Two integers entered by user is stored using scanf() function
    scanf("%d %d", &firstNumber, &secondNumber);

    // sum of two numbers in stored in variable sumOfTwoNumbers
    sumOfTwoNumbers = firstNumber + secondNumber;

    // Displays sum      
    printf("%d + %d = %d", firstNumber, secondNumber, sumOfTwoNumbers);

    return 0;
}

这是调试器日志（如here所述）：

和

（超过最大字符数限制，这就是我在pastebin发布的原因）

当我尝试调试代码时，当有断点时，我得到一个窗口：

The inferior stopped because it received a signal from the operating system.
Signal name: ?
Signal meaning: Unknown signal

另外，我遇到问题：

:-1: error: An exception was triggered: 
Exception at 0x4015f6, code: 0x4000001f: Win32 x86 emulation subsystem breakpoint hit, flags=0x0.

屏幕截图：

还有一些截图：

构建和运行代码不会给我带来任何错误。我读过this但除了Windows Defender之外我没有防病毒软件，我禁用了它的实时保护。我使用Windows 8.1

我还使用msys2中的QT，mingw和gdb。

问题：问题是什么以及如何解决？
