Fixed by moving update_key_parts() down to be after write_index(). myisam/sort.c: write_index() collects index statistic which is further used in update_key_parts(). Thus update_key_parts() must be called after write_index(). mysql-test/r/repair.result: Test case for bug#18874. mysql-test/t/repair.test: Test case for bug#18874.
