Alexander Barkov added a comment - 2022-03-12 11:22 The crash is repeatable with utf32_general_ci instead of utf32_myanmar_ci: DROP TABLE IF EXISTS t1; CREATE TABLE t1 (a CHAR (1)); SET COLLATION_CONNECTION=utf32_general_ci, CHARACTER_SET_CLIENT= binary ; ALTER TABLE t1 CHANGE a a ENUM( 'a' , 'a' ) CHARACTER SET utf32;

Alexander Barkov added a comment - 2022-03-14 13:48 This problem: SET sql_mode= '' ; CREATE TABLE t (HOST CHAR DEFAULT '%' , USER CHAR DEFAULT '%' ,ROLE CHAR DEFAULT '%' ,ENABLED ENUM ( 'a' , 'a' ) DEFAULT 'a' ,HISTORY ENUM ( 'a' , 'a' ) DEFAULT 'a' ) ROW_FORMAT= DYNAMIC COLLATE =utf32_unicode_nopad_ci ENGINE=InnoDB; INSERT INTO t SELECT * FROM t; is now reported as a separate issue MDEV-28062 .
