 Description   

step to reproduce:

CREATE TABLE v0 ( v1 INT NULL UNIQUE CHECK ( COLLATION ( CONVERT ( INET6_NTOA ( ( TRUE & 'x' ) ) REGEXP 'x' , FLOAT ) ) = 'x' ) ) ;
 
 UPDATE v0 SET v1 = v1 + 0 ;
 
 CREATE TABLE v2 ( v3 SET ( 'x' ) NULL CHECK ( round ( 'x' , 'x' IN ( 'x' * 'x' , -1 , NULL ) ) = 8 ) ) ;
 
 SELECT 'x' FROM v2 GROUP BY v3 HAVING v3 = FORMAT ( SPACE ( 59688264.000000 / ( NOT DEFAULT ( v3 ) ) ) , -128 ) ;
 
 INSERT INTO v0 VALUES ( 83 ) ;
 
 DROP PROCEDURE v0 ;

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.

Thank you for the report! I repeated on 10.4-10.6, 10.2 and 10.3 work as expected.

 CREATE TABLE t1 ( v3 SET ( 'x' ) NULL CHECK ( round ( 'x' , 'x' IN ( 'x' * 'x' , -1 , NULL ) ) = 8 ) ) ;
 
 SELECT 'x' FROM t1 GROUP BY v3 HAVING v3 = FORMAT ( SPACE ( 59688264.000000 / ( NOT DEFAULT ( v3 ) ) ) , -128 ) ;
