x8会声会影为何显示盗版

Posted 2023-04-09

参考技术A 破解失败。
其实第一次Coreldraw x8弹出盗版提示，就是软件已经检测出你当前使用的是盗版，但是这个缓存，是会写进你的电脑里面的，所以第二次不联网的前提下直接弹出这个对话框，不用想肯定是调用了某一个缓存。这个软件的破解版现在网上基本已经没有了，所以正在使用的，如果不解决这个盗版弹窗的问题，几乎可以说无法永久使用的。包括现在的Coreldraw 2021版。

gdb不知为何显示2次析构

gdb不知为何显示2次析构

(金庆的专栏 2016.11)

gdb 显示2次 A::~A():

(gdb) bt
#0  A::~A (this=0x602010, __in_chrg=<optimized out>) at main.cpp:10
#1  0x0000000000400a96 in A::~A (this=0x602010, __in_chrg=<optimized out>)
    at main.cpp:12
#2  0x00000000004009c0 in main () at main.cpp:18

代码如下：

class A
{
public:
    A() {}
    virtual ~A() 
    {
        cout << "~A()" << endl;
    }
};

int main()
{
    A* p = new A;
    delete p;
    return 0;
}

打断点显示：2 locations:

(gdb) b A::~A
Breakpoint 1 at 0x400a40: A::~A. (2 locations)

完整的 gdb 输出:

虚析构函数并且是delete才这样。
