When table2myisam() prepares recinfo structures BIT field was skipped because pack_length_in_rec() returns 0. Instead of BIT field DB_ROW_HASH_1 field was taken into recinfo structure and its length was added to reclength. This is wrong because not stored fields must not be prepared as record columns (MI_COLUMNDEF) in storage layer. 0-length fields are prepared in "reserve space for null bits" branch. The problem only occurs with tables where there is no data for the main record outside of the null bits. The fix updates minpos condition so we avoid fields after stored_rec_length and these are not stored by definition. share->reclength already includes not stored lengths from CREATE TABLE so we cannot use it as minpos starting point. In Aria there is no "reserve space for null bits" and it does not create column definition for BIT. Also there is no setup_vcols_for_repair() to reproduce the issue. But nonetheless it creates column definition for not stored fields redundantly, so we patch table2maria() as well. The test case for Aria tries to demonstrate BIT field works, it does not reproduce any issues (as redundant column definition for not stored field seem to not cause any problems).
