    Description

      MariaDB debug build (12.2.2-MariaDB-asan-debug) crashes with an assertion failure when using FLOOR function on CURRENT_TIME result in a CTE with Aria engine. The assertion `maybe_null() || !null_value` fails in `Item_func_floor::time_op()`.

      DROP DATABASE IF EXISTS sqlcraft;
      CREATE DATABASE sqlcraft;
      USE sqlcraft;
      CREATE TABLE t0(c0 SMALLINT  PRIMARY KEY) engine=Aria;
       
       
      WITH tom2 AS ( SELECT  tom1.c0 AS c1 FROM ( SELECT CURRENT_TIME( 2 ) AS c0 FROM t0 AS tom0 LIMIT 42 ) AS tom1 )
      SELECT LEAST( IFNULL( '2025' , MIN( '2025' ) ) , MIN( '2025' ) , MIN( '2025' ) ) AS c14 
      FROM tom2 AS tom16 
      WHERE FLOOR( tom16.c1 ) 
      GROUP BY tom16.c1 
      HAVING ADDTIME( '2025-12-31 14:30:00' , '14:30:00' ) 
      ORDER BY c14 DESC LIMIT 4;
