由于 "Unknown signal"，使用 dgb 在 QT Creator 中调试时出错

Question

我正在尝试调试这段代码：

#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;
}

这里是调试器日志（如here所述）：

当我尝试调试代码并且存在断点时，我得到一个 window:

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

此外，我遇到问题：

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

还有一些截图：

构建和运行代码没有给我任何错误。我已阅读 this 但我没有除 Windows Defender 以外的防病毒软件，我禁用了它的实时保护。我用 Windows 8.1

我还使用 msys2 的 QT、mingw 和 gdb。

问题：问题是什么，如何解决？

Answer 1

我使用的是 qtcreator 64 位，但项目选择了套件 mingw-w64 32 位。我认为位数的差异导致了错误。

现在，当我将 qtcreator 64 位与套件 mingw-w64 64 位一起使用时，调试器工作正常

我得到了 Reddit user jedwardsol 的帮助：

4000001f is coming from the x86 emulation layer of 64-bit Windows. Perhaps your debugger doesn't understand it.

Try building a 64-bit program instead.
