应用错误收集

队

我正在尝试使用mysqlclient版本16和Mysql c ++连接器连接到Mysql数据库并执行一些数据库操作。我们已经编写了依赖这些库的产品代码。 Mysql Server版本5.1.56。我可以看到它在各种场合都会崩溃。

以下是几个崩溃转储。知道为什么会这样吗？通常在关闭连接期间创建连接。

为了紧密连接，我使用mSqlCon-＆gt; close（）
使用以下内容创建连接iam：

driver = get_driver_instance（）; mSqlCon = driver-＆gt; connect（connection_properties）;

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