How to repeat:
DROP DATABASE test;CREATE DATABASE test;USE test;
CREATE TABLE t1(bitk bit,bit bit,key (bitk))ENGINE=InnoDB;
ALTER TABLE t1 ADD COLUMN a int unsigned;
alter table t1 add key(a);
insert into t1 values(1,0,0);
alter TABLE t1 modify a int auto_increment,engine=myisam,comment="new myisam table";

Hello Ramesh Sivaraman,

Thank you for the report and test case.
Confirmed that 5.6.23/5.7.6 debug builds are affected.

Thanks,
