      Description

      Trivial debug-only issue it seems, but with varied outcomes.

      # mysqld options required for replay:  --innodb-data-file-size-debug=-1   # or other larger negative values
      

      Leads to (on debug):

      Affected versions 10.1-10.5 (debug), in various ways. Using this option on debug creates all sort of issues (out of disk space, defunct mysqld processes, issues with data init etc.). Had to restart server in the end to cleanup state.

      MariaDB 10.1 debug gives this :

      2020-05-08  8:00:45 23305409935296 [Note] InnoDB: innodb_empty_free_list_algorithm has been changed to legacy because of small buffer pool size. In order to use backoff, increase buffer pool at least up to 20MB.
      

      But then starts filling up the disk;

      -rw-rw---- 1 roel roel  50G May  8 08:02 ibdata1
      

      And counting - Likely due to the negative->to->max var.

      Also seen;

      Fix may be as easy as disabling <0 values?
