Server crashes in Field::register_field_in_read_map upon select from partitioned table with indexed by prefix virtual column. After several read-mark fixes a problem has surfaced: Since KEY (c(10),a) uses only a prefix of c, a new field is created, duplicated from table->field[3], with a new length. However, vcol_inco->expr is not copied. Therefore, (*key_info)->key_part[i].field->vcol_info->expr was left NULL in ha_partition::index_init(). Solution: copy vcol_info from table field when it's set up.
