Question

我正在尝试使用fstream和异常，但始终使用崩溃崩溃的异常运行程序，编译器未报告错误。我认为是MinGw编译器中的错误或与Windows系统的兼容性。

您能帮我解决我的问题吗？谢谢！

代码:::阻止17.12！修订版11256 Win32 / gcc版本3.4.5（mingw-vista special r3）/ Windows 7 ServicePack1

示例代码：

#include <iostream>
#include <fstream>

int main() {
    int ivalue;
    try {
        std::ifstream in("in.txt");
        in.exceptions(std::ifstream::failbit);
        in >> ivalue;
    } catch (std::ios_base::failure &fail) {
        // handle exception here
    }
}
```
