C++ 头文件中断一个程序，但在另一个程序中工作

我有下面的头文件-

#pragma once
#include <vector>

template<int rows, int cols = rows>
class mat {
public:
    mat() : values{ rows, std::vector<double>(cols) } {
        if (rows == cols) {
            int y = 0;
            for (int x = 0; x < rows; x++) {
                values[x][y] = 1;
                y++;
            }
        }
    }
    mat(int val) : values{ rows, std::vector<double>(cols, val) } {}
    std::vector<double> &operator[](int x) {
        return values[x];
    }
private:
    std::vector<std::vector<double>> values;
};

这是我引用的main.cpp文件-

mat<5> mat5;

for (int y = 0; y < 5; y++) {
    for (int x = 0; x < 5; x++) {
        std::cout << mat5[x][y] << ", ";
    }
    std::cout << std::endl;
}

解决办法相当简单。我之所以使用静态C运行库，是因为我认为在静态链接SDL2时需要这样做。事实上，您需要将/MD用于多线程DLL，并始终与SDL2一起使用。

Smth尝试释放以前未在此地址分配的内存。某些全局对象可能会破坏您的程序，而您尚未发布。我的系统中没有全局对象code@S.M.我的意思是，如果你想让我发布所有的代码，我不认为这是必要的，但我发布了github，以便有人可以在需要时查看整个代码。问题是，没有任何东西被释放。我可能很蠢，但到目前为止，代码中没有其他内容。它天生就是在调试器中运行的。好吧，我看了一下你的github。SDL2手册：将C运行时设置为“多线程DLL”。您的cmake:

set（cmake\u CXX\u FLAGS\u DEBUG）/MTd“

，

set（cmake\u CXX\u FLAGS\u RELEASE）/MT”）

。

mat<5> mat5;

for (int y = 0; y < 5; y++) {
    for (int x = 0; x < 5; x++) {
        std::cout << mat5[x][y] << ", ";
    }
    std::cout << std::endl;
}
