    Details

      Description

      step to reproduce:

      CREATE TEMPORARY TABLE v0 ( v1 TEXT ( 15 ) CHAR SET BINARY NOT NULL NOT NULL UNIQUE CHECK ( v1 ) ) REPLACE SELECT NULL AS v3 , 74 AS v2 ;
       SELECT SQL_CALC_FOUND_ROWS * FROM v0 WHERE v1 IN ( SELECT v3 FROM v0 ) LIMIT 16 ;
       DROP PROCEDURE v0 ;
       CREATE TABLE v4 ( v6 INT , v5 INT DEFAULT 27 ) ;
       ROLLBACK TO SAVEPOINT v4 ;
       INSERT INTO v4 VALUES ( + 84 , + 32 , 48 ) ;
      

      report (compiled with ASAN):

      Server version: 10.7.0-MariaDB
      key_buffer_size=134217728
      read_buffer_size=131072
      max_used_connections=1
      max_threads=153
      thread_count=1
      It is possible that mysqld could use up to 
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467956 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
