    Description

      A 10.1.28 Slave of a 10.0.32 Master crashes with:

      InnoDB: Error: trying to access update undo rec field 38 in index "CLUST_IND" of table "SYS_INDEXES"
      InnoDB: but index has only 9 fields
      InnoDB: Submit a detailed bug report to http://bugs.mysql.com
      InnoDB: Run also CHECK TABLE "SYS_INDEXES"
      InnoDB: n_fields = 11, i = 0, ptr 0x7ef432c82c81

      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: 10.1.28-MariaDB-1~jessie
      key_buffer_size=134217728
      read_buffer_size=131072
      max_used_connections=120
      max_threads=2050
      thread_count=32
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 4634132 K bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.

      where mysqld died. If you see no messages after this, something went
      terribly wrong...
