memcpy(）给了我seg错误

我的程序是OpenGL程序，当我不使用memcopy时，它会编译并运行良好，但当程序中使用此函数时，当我在编译后尝试运行程序时，它给了我一个seg错误，在这两种情况下，它仍然会编译，但当我使用此函数编译程序时，会给我一个seg错误，在gdb中检查时的seg错误并没有显示memcpy是问题所在，而是显示了一个初始化函数init()，它为我创建了opengl上下文，但奇怪的是，只有当我在程序中包含memcpy并对其进行编译时，才会发生这种情况，否则init()工作正常，我还在另一个文件中测试了它，以确认它在自己的上工作

我不知道它为什么这么做，我确实注意到，自从linux mint升级了一些包之后，就发生了这种情况，在升级之前，程序运行良好

这是程序源代码

当我运行gdb时，这就是它给出的问题，尽管当我注释出memcpy时，它工作得很好，不会给我任何seg错误
