In debug builds, let us declare dict_sys.latch as index_lock instead of srw_lock, so that we will benefit from the full tracking of lock ownership. lock_table_for_trx(): Assert that the current thread is not holding dict_sys.latch. If the dict_sys.unfreeze() call were moved to the end of lock_table_children(), this assertion would fail in the test innodb.innodb and many other tests that use FOREIGN KEY.
