【问题描述】：
当我尝试从现有数据库生成实体模型时，mysqld 服务崩溃。 MySQL 8.0.20 不会出现这种情况，只有 8.0.21 才会出现这种情况。我希望使用更新中添加的新 json 功能，但这个问题让我抓狂。
实体向导与服务器连接正常并显示我要导入的表，当导入过程开始时抛出异常“连接丢失”并且我看到 mysqld.exe 已停止。
除了向导生成的部分查询之外，MySQL 日志没有显示任何有用的信息：
15:45:58 UTC - mysqld got exception 0xc0000005 ;
Most likely, you have hit a bug, but this error can also be caused by malfunctioning hardware.
Thread pointer: 0x1c9945fcfc0
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

这是我的错误还是某种配置错误？

如果这是 8.0.21（而不是 8.0.20）中新增的 mysqld.exe 崩溃，最好将其报告给 MySQL 错误跟踪器：bugs.mysql.com/report.php跨度>
