0000005：在OCTREE.exe 0x1000bbae未处理的异常访问冲突写入位置0x0000

我得到上线下面的代码上面运行时错误：

glutMainLoop();

为什么？

Answer 1:

我没有用GLUT 7年，所以把我的答案与一粒盐。这就是说，你init()函数让我有点担心。我相信，当你写GLUT程序，你应该只在发出过剩回调函数OpenGL命令。我不知道有当你主动OpenGL上下文init()函数被执行。方案是否崩溃，如果你删除调用init()

Answer 2:

你得到一个异常试图在0x000000a8写。正在发生的事情是什么地方你的代码或OpenGL是接收一个空指针，而不是一个有效的指针。有问题的代码试图更新在从该指针的东西的168（0xa8）所抵消。
