GDB在DEV c++中停止运行

我最近开始在DEV c++中编程，我遇到了一个问题，在这里搜索谷歌还没有证明有帮助。

在下面的代码中，GDB在到达第5行std::cout << "Hello" << std::endl;时"挂起"。

#include <iostream>
int main()
{
    int tree = 9;
    std::cout << "Hello" << std::endl;
    tree = 10;
    return 0;
}

程序编译并运行得很好，但是当分步执行时，它总是卡在这里，"Next line"或"Continue"似乎都不起作用。

下面是GDB窗口的一些输出:

我对GDB很陌生。这是GDB的一个特性吗?我设置错了吗?这是怎么回事?

我祈祷不是我犯了什么愚蠢的错误
