      Description

      The failure was incidentally fixed in 10.3+ in the scope of MDEV-24958. However, while MDEV-24958 was a regression in 10.3, this test case is slightly different and it was failing on 10.2+ before the regression in 10.3 occurred, thus it kept failing on 10.2 after it was fixed in 10.3+.

      I don't think the test case has any real-life significance, and since higher versions aren't affected, I don't expect it to be fixed in 10.2. It's filed as a formality, and so that we don't need to chase it again when it's encountered in 10.2 tests.

      CREATE TABLE t1 (b BLOB NOT NULL DEFAULT '');
      SELECT DEFAULT(b) AS f FROM t1 HAVING f > 5;
       
      # Cleanup
      DROP TABLE t1;

      210417 19:39:34 [ERROR] mysqld got signal 6 ;
      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: 10.2.38-MariaDB-debug-log
      key_buffer_size=1048576
      read_buffer_size=131072
      max_used_connections=1
      max_threads=153
      thread_count=1
      It is possible that mysqld could use up to 
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 63104 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...
