      Description

      I tried to run this query:

      SELECT
          b.ekperif, s.short_description, s.imagesXrwma
      FROM
          (SELECT
              ps.synolo,
                  se.id_syndiasmosSeEnotita,
                  se.id_syndiasmos,
                  se.id_perifereiakiEnotita,
                  se.id_eklogikhPerifereia
          FROM
              (SELECT
              SUM(ps.psifoiSyndiasmou) AS synolo,
                  ps.id_syndiasmosSeEnotita
          FROM
              psifoiSyndiasmon AS ps
          WHERE
              ps.id_diexagogiEklogon = 3
          GROUP BY (ps.id_syndiasmosSeEnotita)) AS ps
          LEFT JOIN syndiasmosSeEnotita se ON ps.id_syndiasmosSeEnotita =
      se.id_syndiasmosSeEnotita
          WHERE
              se.active = 1) AS a
              INNER JOIN
          (SELECT
              MAX(t.synolo) AS maxsynolo,
                  t.id_eklogikhPerifereia AS ekperif
          FROM
              (SELECT
              ps.synolo,
                  se.id_syndiasmosSeEnotita,
                  se.id_syndiasmos,
                  se.id_perifereiakiEnotita,
                  se.id_eklogikhPerifereia
          FROM
              (SELECT
              SUM(ps.psifoiSyndiasmou) AS synolo,
                  ps.id_syndiasmosSeEnotita
          FROM
              psifoiSyndiasmon AS ps
          WHERE
              ps.id_diexagogiEklogon = 3
          GROUP BY (ps.id_syndiasmosSeEnotita)) AS ps
          LEFT JOIN syndiasmosSeEnotita se ON ps.id_syndiasmosSeEnotita =
      se.id_syndiasmosSeEnotita
          WHERE
              se.active = 1) AS t
          GROUP BY t.id_eklogikhPerifereia) AS b ON a.id_eklogikhPerifereia =
      b.ekperif
              LEFT JOIN
          syndiasmos s ON a.id_syndiasmos = s.id_syndiasmos
      WHERE
          a.synolo = b.maxsynolo;
      

      and the server crashed. Log:

      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: 5.5.35-MariaDB-log

      max_used_connections=1
      max_threads=52
      thread_count=1
      It is possible that mysqld could use up to 
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 138638 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
