    Description

      To reproduce the bug report, unpack the .7z archive file attached to the linked bug report, start MariaDB server and run the following statements to prepare environment:

      $ mysql -e 'CREATE DATABASE local_portal' -u root
      		 
       
      		 
      $ mysql -u root local_portal < /path/to/dir/where/archive/was/extracted/tableSchemaAndData-mariaDbTest
      		 
      $ mysql -u root local_portal < /path/to/dir/where/archive/was/extracted/item_creation_retailer_group_retailers_mariadbtest.sql
      		 
      $ mysql -u root local_portal < /path/to/dir/where/archive/was/extracted/qry_exporterImages-mariaDb_storedProcIssue.sql
      		 
      $ mysql -u root local_portal < /path/to/dir/where/archive/was/extracted/vu_productimages_retailergroup-mariaDb-storedProcIssue.sql
      		 
       
      		 
      $ mysql -u root local_portal
      		 
      MariaDB [local_portal]> CALL qry_exporterImages_mariaDbTest(3569,4,628);
      		 
      MariaDB [local_portal]> CALL qry_exporterImages_mariaDbTest(3569,4,628);

      Result sets returned on the first and the second invocation of the stored routine qry_exporterImages_mariaDbTest are different (at least, number of rows returned by two invocations are different)
