    Description

      MariaDB debug build (12.2.2-MariaDB-asan-debug) crashes with an assertion failure when performing XOR operation between MAX function result and JSON_OBJECTAGG. The assertion `(m_ptr == __null) == item->null_value` fails in `VDec::VDec(Item*)`.

      DROP DATABASE IF EXISTS sqlcraft;
      CREATE DATABASE sqlcraft;
      USE sqlcraft;
      CREATE TABLE IF NOT EXISTS t0(c0 VARCHAR(100)  NOT NULL, c1 INT );
       
      SELECT  ( MAX( 'A' ) ) ^ ( JSON_OBJECTAGG( 1 ,1 ) )  AS c19 FROM t0 AS tom19   ;
      

      crash logs:
