Description
Note: I'm not sure it's actually an InnoDB problem, please change the category and re-assign if needed.
To reproduce,
- create a datadir with the default innodb_undo_tablespaces=0,
- start the server with another value, e.g. --innodb_undo_tablespaces=2.
The error is expected in this case, but what happens after it appears to be wrong.
On 10.2:

On 10.1, there is no assertion failure or ref_count problem, but it seems that the process just disappears without proper shut down:
