再发一帖，libmysqlclient 奇怪问题，求助大牛，百思不得其解

我又多番研究，找到一点蛛丝马迹，会不会和“结构体对齐”或者“c++对象内存布局”有点关系，但是我目前所学知识还不能理解这个现象，分隔线上面和下面有啥区别？？？

各位看看下面代码：

struct test_struct
{
    MYSQL fuck_mysql;
    int   fuck_int;
};

void foo()
{
    test_struct ts;
    ts.fuck_int = 0;
    if (!mysql_init(&ts.fuck_mysql))
    {
        cout << "mysql_init error. ret:" << string(mysql_error(&ts.fuck_mysql)) << endl;
    }
    if (!mysql_real_connect(&ts.fuck_mysql,
                           "192.168.111.120",
                           "root",
                           "123",
                           0,
                           3306, NULL, 0))
    {
        cout << "mysql_real_connect error. ret:" << string(mysql_error(&ts.fuck_mysql)) << endl;
    }
    cout << "ts.fuck_int:" << ts.fuck_int << endl;

    cout << "-----------------------------------分隔线-----------------------------------------------" << endl;

    int before = 0;
    MYSQL connection;
    int after = 0;
    if (!mysql_init(&connection))
    {
        cout << "mysql_init error. ret:" << string(mysql_error(&connection)) << endl;
    }
    if (!mysql_real_connect(&connection,
                           "192.168.111.120",
                           "root",
                           "123",
                           0,
                           3306, NULL, 0))
    {
        cout << "mysql_real_connect error. ret:" << string(mysql_error(&connection)) << endl;
    }
    cout << "before:" << before << endl;
    cout << "after:" << after << endl;

}

得到结果是：
ts.fuck_int:17765728
-----------------------------------分隔线-----------------------------------------------
before:0
after:0

这个地方，fuck_int和after有啥区别呢？？？
