Crash on 2-nd execution of SP/PS for query calculating window functions from view

    Details

      Description

      When the stored procedure that does nothing but passing few parameters to complex SELECT with several CTEs is called for the second time:

      MariaDB [(none)]> CALL db.P_NAME4('ALL','ALL','something','20210427','20210428','ALL');
      ...
      4 rows in set (3.102 sec)
       
      Query OK, 0 rows affected (3.102 sec)
       
      MariaDB [(none)]> CALL db.P_NAME4(NULL,NULL,NULL,NULL,NULL,NULL);
      ERROR 2013 (HY000): Lost connection to MySQL server during query
      

      it crashes, with the following stack trace:

       
      210429 14:37:00 [ERROR] mysqld got signal 11 ;
      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: 10.5.9-6-MariaDB-enterprise-log
      key_buffer_size=1073741824
      read_buffer_size=2097152
      max_used_connections=84
      max_threads=65537
      thread_count=101
      It is possible that mysqld could use up to 
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 940638017 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...
