      mysqltest: At line 42: query 'CHECK TABLE tz,tr,td' failed: 2013: Lost connection to MySQL server during query
       
      The result from queries just before the failure was:
      < snip >
      INSERT INTO tr(id) select * from seq_1_to_10000;
      CREATE TABLE td(id BIGINT PRIMARY KEY, i INT)

      CREATE PROCEDURE a()
      BEGIN
      ALTER TABLE tz ADD INDEX(i);
      ALTER TABLE tr ADD INDEX(i);
      ALTER TABLE td ADD INDEX(i);

      2020-09-10 12:59:37 8 [ERROR] [FATAL] InnoDB: Trying to read page number 28 in space 7, space name test/td, which is outside the tablespace bounds. Byte offset 0, len 16384

      This could be because you hit a bug. It is also possible that this binary
      or one of the libraries it was linked against is corrupt, improperly built,
      or misconfigured. This error can also be caused by malfunctioning hardware.
       
      To report this bug, see https://mariadb.com/kb/en/reporting-bugs
       
      We will try our best to scrape up some info that will hopefully help
      diagnose the problem, but since we have already crashed, 
      something is definitely wrong and this may fail.
       
      Server version: 10.4.15-MariaDB-debug-log
      key_buffer_size=1048576
      read_buffer_size=131072
      max_used_connections=1
      max_threads=153
      thread_count=7
      It is possible that mysqld could use up to 
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 62222 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.

      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...
