After iterating all fields and setting PART_INDIRECT_KEY_FLAG as necessary, TABLE::mark_columns_used_by_virtual_fields() remembers in TABLE_SHARE that this operation was done and need not be repeated. But as the flag is set in TABLE_SHARE, PART_INDIRECT_KEY_FLAG must be set in TABLE_SHARE::field[], not only in TABLE::field[]. Otherwise all new TABLEs opened from this TABLE_SHARE will never have it.
