    Details

      Description

      From the log :

      191112 21:24:03 [ERROR] mysqld got exception 0xc0000005 ;
      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: 10.4.10-MariaDB
      key_buffer_size=134217728
      read_buffer_size=131072
      max_used_connections=1
      max_threads=65537
      thread_count=7
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 136385 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...

      InnoDB: using atomic writes.

      What I tried to do:
      create empty table with the same columnts - works
      remove the fulltext search - works
      remove the where ... in ... - works
      remove the city or change the city= to city in (...) - not work
      remove some of the fields from the SELECT - not work
      remove thr ORDER BY and the computed column for it - not work
      tested with a 20 rows - works
      30 rows - works
      50 rows - crashed
      start again - works
      touch the table (INSERT, DELETE row, etc) - crashed again

      Tested on 10.3 - works

      Scheme used for testing:

      CREATE TABLE `search_sites2` (
      `id` int(11) NOT NULL,
      `name` varchar(75) NOT NULL,
      `company` varchar(50) NOT NULL DEFAULT ' ',
      `description` text DEFAULT NULL,
      `require` text DEFAULT NULL,
      `has_phone` tinyint(1) NOT NULL,
      `has_mail` tinyint(1) NOT NULL,
      `mail` varchar(70) NOT NULL,
      `home` tinyint(3) unsigned NOT NULL,
      `visible` tinyint(1) DEFAULT NULL,
      `link` varchar(100) DEFAULT NULL,
      `manpower` tinyint(3) unsigned NOT NULL,
      `start_date` datetime NOT NULL,
      `update_date` datetime NOT NULL,
      `require_cv` tinyint(3) unsigned NOT NULL,
      `parent` int(11) NOT NULL,
      `code` varchar(25) NOT NULL,
      `submit_url` varchar(250) NOT NULL,
      `x` double NOT NULL,
      `y` double NOT NULL,
      `address` varchar(90) DEFAULT NULL,
      `address_id` int(11) DEFAULT NULL,
      `sa_id` int(11) NOT NULL,
      `a_point` point NOT NULL,
      `city` int(11) DEFAULT NULL,
      `city_name` varchar(50) NOT NULL,
      `area` int(10) unsigned DEFAULT NULL,
      `parent_area` int(10) unsigned DEFAULT NULL,
      `company_id` int(11) NOT NULL,
      `company_orig_name` varchar(50) DEFAULT NULL,
      `logo` int(11) DEFAULT NULL,
      `parent_id` int(11) DEFAULT NULL,
      `company_personal` tinyint(3) unsigned DEFAULT NULL,
      PRIMARY KEY (`sa_id`),
      KEY `site_id` (`id`),
      SPATIAL KEY `point` (`a_point`),
      KEY `city` (`city`),
      KEY `update_date` (`update_date`),
      KEY `home` (`home`),
      KEY `company` (`company_id`),
      FULLTEXT KEY `fts` (`name`,`description`,`company`,`require`,`address`,`city_name`,`company_orig_name`)
      ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

      CREATE TABLE `search_sites3` (
      `st_id` int(11) NOT NULL DEFAULT 0,
      `st_site` int(11) NOT NULL,
      `st_type` int(11) NOT NULL,
      `st_speciality` int(11) NOT NULL,
      `st_site_visible` tinyint(1) NOT NULL DEFAULT 1
      ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

      I can send the table content, but not in public place.
