    Description

      Hi,

      Running the following test case crashes the MariaDB server:

      DROP DATABASE IF EXISTS test1;
      CREATE DATABASE test1;
      USE test1;
       
      SELECT JSON_SET('{"c":4}', '$.a', 5) AS x
      HAVING (x IN (JSON_KEY_VALUE(x, '$'), ','));
      

      This is the log:
