      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: 10.1.23-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 = 5297 K bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.

      Thread pointer: 0x0
      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...

          Since you got a core dump, maybe could you provide the gdb stacktrace of the dump?

          If you tell me how to do it and where I find the dump file I can try.

          "Aborted (core dumped)" message from the shell, so this should be a usual place where your Linux saves core files. maybe current directory. Maybe executable directory. I'm not sure where
