问题描述
我知道这个问题在这些论坛上被评估了很多次，但是它们对于大多数时候的具体案例来说都是独一无二的。
I know this problem is assessed many times on these forums, but they really are unique to their specific cases most times.
这是一个类的项目在C ++中不少），而且这个项目的重点是重写经典的棋盘游戏Reversi。
This is a project for a class (on C++ no less), and the point of the project was to remake the classic board game Reversi.
我已经通过代码修剪了几个小时，最后制作了一个程序，工作，所以我想！
I have toiled through code for hours and finally made a program that will work, or so I thought!
我遇到的大问题似乎来自我的解构程序，因为它给我这个错误，我们很多人看到。我的代码发布在下面和我自己的调试代码（使用有用的cout消息）我已经确定该程序运行到Game.cpp类的最后。只有，它在解构器上崩溃，最后才结束。
The big problem I am having seems to come from my deconstructor as it's giving me this error many of us have seen. My code is posted below and from my own debugging code (using helpful cout messages) I have determined that the program manages to run to the end of the the Game.cpp class. Only, it stumbles on the deconstructor and crashes before finally "ending nicely".

对于极端的代码，我深表歉意，但在这一点上，不知道该怎么解决我知道这里也有不好的编码习惯，所以如果你看到任何的话，我会喜欢建设性的批评。
I apologize for the extreme amount of code, but at this point, I don't know what to fix. I know there might also be bad coding habits here, so if you see any, I would love the constructive criticism.
提前谢谢你所有的帮助！
Thank you in advance for all your help!!
推荐答案
这是可能，因为您在 / code> class：
This is probably because you have these declarations in the Game class:
Board b;
Player *p1;
Player *p2;
这个代码在析构函数中：
and this code in the destructor:
delete &b;
delete &p1;
delete &p2;
首先，董事会 code> b 不是一个指针，所以不应该被删除。其次，您正在使用地址操作符来获取指针的地址 （它将是一个类型为$ code> Player ** ），你不分配。删除& 。
First of all, the Board member b is not a pointer so should not be deleted. Second of all, you're using the address-of operator to get the address of the pointer (and it will be a value of type Player**), which you don't allocate. Drop the &.
