      To reproduce (Use RQG repo and branch as described, other versions may behave differently):

      git clone https://github.com/MariaDB/randgen --branch mdev20737 rqg-mdev20737
      cd rqg-mdev20737
      perl ./runall-new.pl --basedir=<your basedir> --threads=8 --duration=250 --engine=Aria --seed=1 --scenario=CrashUpgrade --grammar=mdev20737.yy --skip-gendata --gendata-advanced --mysqld=--aria-encrypt-tables=1 --mysqld=--file-key-management --mysqld=--file-key-management-filename=`pwd`/data/file_key_management_keys.txt --mysqld=--plugin-load-add=file_key_management --vardir=/dev/shm/vardir_mdev20737
      

      Remember to set the basedir in the command line above.

      Sometimes it can fail instead with

      Got error 192 when executing record redo_index_new_page
      

      or

      Got error 192 when executing record redo_new_row_tail
      

      or

      Got error 126 when executing undo undo_key_insert
      

      Just re-run it if it happens.

      If it doesn't fail as needed in 1-2 attempts, try pointing vardir at disk rather than shm. It fails for me almost every time either way, so I can't say how more probable it is on disk, but it seems that it can be.

      Reproducible on 10.1-10.5.
      Couldn't reproduce without encryption.
