AddressSanitizer: use-after-poison upon update after an error with SIMULTANEOUS_ASSIGNMENT

Details

    Description

      Note: The most of the stack trace closely resembles MDEV-16694, but given the top frames (in create_tmp_table and a very different test case, I'm not sure at all it's the same issue, so filing it separately. See also MDEV-22600 for a variety of test cases very similar to this one, with different failures.

      CREATE TABLE t1 (a INT);
      		 
      CREATE TABLE t2 (d DATE NOT NULL, g GEOMETRY);
      		 
      INSERT INTO t2 VALUES ('1981-09-12',NULL);
      		 
       
      		 
      SET SQL_MODE= 'SIMULTANEOUS_ASSIGNMENT,STRICT_ALL_TABLES';

      UPDATE t2 SET d = NULL, g = 42;

      Both debug- and non-debug ASAN builds are affected.
      No obvious problem on a non-ASAN build.
      Reproducible on 10.3-10.5. The test case is not applicable to 10.2 due to SIMULTANEOUS_ASSIGNMENT.
