Crash while loading mysqldump backup when InnoDB encryption is enabled

    Details

    • Sprint:
      10.1.20

      Description

      A user saw the following crash when loading a mysqldump backup with encryption enabled in MariaDB 10.1.8:

      160919 17:28:30 [ERROR] mysqld got signal 11 ;
      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 http://kb.askmonty.org/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: 10.1.8-MariaDB-log

      read_buffer_size=262144
      max_used_connections=281
      max_threads=502
      thread_count=65
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 171895 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

      After upgrading to 10.1.17, it is still crashing, but the stack trace is not as useful:
