团队，

我正在尝试使用 mysqlclient 版本 16 和 Mysql c++ 连接器连接到 Mysql 数据库并执行一些 DB 操作。我们的产品依赖于这些库的代码已经编写好了。Mysql 服务器版本 5.1.56。我可以看到它在各种场合都崩溃了。

下面是几个崩溃转储。知道为什么会发生这些吗？通常在关闭连接和创建连接期间。

  1. 对于关闭连接，我使用 mSqlCon->close()

  2. 对于使用以下内容创建连接 iam：

    驱动程序 = get_driver_instance(); mSqlCon = driver->connect(connection_properties);

mSqlCon 的类型为 sql::Connection *。任何帮助表示赞赏！
