      The same test case with an explicit PK doesn't crash, but the error is still there:

      --source include/have_innodb.inc
       
      CREATE TABLE t1 (pk INT PRIMARY KEY, a INT, b INT, c CHAR(8), KEY ind1(c), KEY ind2(b)) ENGINE=InnoDB;
      ALTER TABLE t1 RENAME INDEX ind2 TO ind3, RENAME INDEX ind1 TO ind2;
      UPDATE t1 SET a = 1 WHERE c = 'foo';
       
      # Cleanup
      DROP TABLE t1;

      A similar test case with a longer CHAR causes a SIGSEGV:

      --source include/have_innodb.inc
       
      CREATE TABLE t1 (pk INT PRIMARY KEY, a INT, b INT, c CHAR(64), KEY ind1(c), KEY ind2(b)) ENGINE=InnoDB;
      ALTER TABLE t1 RENAME INDEX ind2 TO ind3, RENAME INDEX ind1 TO ind2;
      UPDATE t1 SET a = 1 WHERE c = 'foo';
       
      # Cleanup
      DROP TABLE t1;

      The test case is not applicable to earlier versions due to RENAME INDEX.
