Crash on `CHARACTER SET csname COLLATE DEFAULT` in column definition

    XMLWordPrintable

Details

    Description

      These statements crash the server:

      CREATE OR REPLACE TABLE t1 (a CHAR(10) CHARACTER SET latin1 COLLATE DEFAULT);
      		 
      CREATE OR REPLACE TABLE t1 (a CHAR(10) CHARACTER SET utf8mb4 COLLATE DEFAULT);

      Note, this statements do not:

      CREATE OR REPLACE TABLE t1 (a CHAR(10)) CHARACTER SET utf8mb4 COLLATE DEFAULT;
      		 
      CREATE OR REPLACE TABLE t1 (a CHAR(10)) CHARACTER SET latin1 COLLATE DEFAULT;

      But they can produce a wrong table. See MDEV-27782.
