Description:
We used MySQL's clone feature to perform a data clone. Shortly after running, a crash occurred simultaneously on one primary and two replica servers. We suspect that this issue may be related to a bug in the clone functionality.
InnoDB: We intentionally generate a memory trap.
InnoDB: Submit a detailed bug report to http://bugs.mysql.com.
InnoDB: If you get repeated assertion failures or crashes, even
InnoDB: immediately after the mysqld startup, there may be
InnoDB: corruption in the InnoDB tablespace. Please refer to
InnoDB: http://dev.mysql.com/doc/refman/8.0/en/forcing-innodb-recovery.html
InnoDB: about forcing recovery.

Most likely, you have hit a bug, but this error can also be caused by malfunctioning hardware.
