      The test case is not applicable to non-debug build due to the use of SHOW FUNCTION CODE and to earlier versions due to the use of JSON_TABLE.

            Probably a duplicate of MDEV-23208.

            elenst Elena Stepanova added a comment - Probably a duplicate of MDEV-23208 .

            I ran into this particular one also, with a very similar looking testcase. This issue is 10.6+ only. Very lightly sporadic.

            CREATE VIEW v AS SELECT * FROM JSON_TABLE ('[]','$' COLUMNS (c INT EXISTS PATH '$')) AS d;
            PREPARE p FROM 'SHOW CREATE VIEW v';
            DROP VIEW v;
            EXECUTE p;
            

            Leads to:
