  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: 10.2.27-MariaDB

  key_buffer_size=0

  read_buffer_size=131072

  max_used_connections=0

  max_threads=1

  thread_count=0

  It is possible that mysqld could use up to

  key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 5419 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...
