Table causes maria to crash repeatedly.

    Description

      When accessing mysql without using the -A flag any query I would execute would fail immediately. The error I get using the console is:

      ERROR 2006 (HY000): MySQL server has gone away
      No connection. Trying to reconnect...
      ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111 "Connection refused")

      Any select doesn't work, even a

      select 1;

      However I could see the databases. Use any of the databases. Serg suggested the following:

      [14:53:14] serg: so, try this. run mysql -A.
      [14:53:29] serg: and then, say, SHOW CREATE TABLE for every table in this your database
      [14:53:57] serg: when you get a crash - you know what frm causes it, create a bug report on mariadb.org/jira and attach
      this frm file
      [14:54:03] serg: 10.1.5 won't crash on it

      FYI the date of this conversation was the 14th of May 2015.

      I'm providing the url to the syslog information that I was getting at the time of the issue.

      Hopefully this helps.
