Bug#33717 INSERT...(default) fails for enum. Crashes CSV tables, loads spaces for MyISAM

Browse Source 
Table corruption happens during table reading in ha_tina::find_current_row() func.
Field::store() method returns error(true) if stored value is 0.
The fix:
added special case for enum type which correctly processes 0 value.
Additional fix:
INSERT...(default) and INSERT...() have the same behaviour now for enum type.
