C++ MySQL C++；连接器内存泄漏

我一直在浏览类似的帖子，但找不到任何适合我的问题

我正在尝试制作一个基本的程序，用MySQL数据库进行查询，一切正常，但我有很多内存泄漏

#include <cppconn/driver.h>

#include <crtdbg.h>

int main() {

    {
        sql::Driver* driver = get_driver_instance();
    }

    _CrtDumpMemoryLeaks();
    return 0;
}

#包括
#包括
int main（）{
{
sql:：Driver*Driver=get_Driver_instance（）；
}
_CrtDumpMemoryLeaks（）；
返回0；
}

这是我正在使用的一个小片段。它的其余部分并不真正相关，因为我已经观察到，即使是这一小块代码也会产生大量内存泄漏，正如_CrtDumpMemoryLeaks调用所给出的那样

我得到了64位版本，并使用了动态链接库。我观察到的是，我还需要单独链接boost库，所以我下载了它，并将其“include”目录也放进去

我正在使用VisualStudio2019社区

任何帮助都将不胜感激。干杯

这是运行程序后的输出

Detected memory leaks!

因此，似乎只有通过调用驱动程序类上的单个方法，才有大量内存泄漏。析构函数受到保护，因此我不能对其调用“delete”。

这不是真正的内存泄漏，因为您正在检查“太早”

您可以看到如何实现

get\u driver\u实例
