This is an off-by-one error in dict/dict0dict.c, dict_table_print_low():
for (i = 0; i + 1 < (ulint) table->n_cols; i++) {
dict_col_print_low(table, dict_table_get_nth_col(table, i));
fputs("; ", stderr);
}
The fix is simple: remove the "+ 1" from the loop condition. Then the last column (always DB_ROLL_PTR) will be printed.

Description: InnoDB Table Monitor output includes a section for each InnoDB table. Each section begins with a COLUMNS part that lists table columns, both those defined in the CREATE TABLE statement and those added internally by InnoDB. Before MySQL 5.1, the COLUMNS part lists the DB_ROLL_PTR column that is added internally by InnoDB. For example: TABLE: name SYS_FOREIGN, id 0 11, columns 8, indexes 3, appr.rows 1 COLUMNS: ID: DATA_VARCHAR prtype 1 len 0 prec 0; FOR_NAME: DATA_VARCHAR prtype 1 len 0 prec 0; REF_NAME: DATA_VARCHAR prtype 1 len 0 prec 0; N_COLS: DATA_INT len 4 prec 0; DB_ROW_ID: DATA_SYS DATA_ROW_ID len 6 prec 0; DB_TRX_ID: DATA_SYS DATA_TRX_ID len 6 prec 0; DB_ROLL_PTR: DATA_SYS DATA_ROLL_PTR len 7 prec 0; INDEX: name ID_IND, id 0 11, fields 1/6, type 3 root page 46, appr.key vals 1, leaf pages 1, size pages 1 FIELDS: ID DB_TRX_ID DB_ROLL_PTR FOR_NAME REF_NAME N_COLS ... However, as of MySQL 5.1, DB_ROLL_PTR is missing from COLUMNS, even though it is used (as shown by the definition of the clustered index): TABLE: name SYS_FOREIGN, id 0 11, columns 7, indexes 3, appr.rows 1 COLUMNS: ID: DATA_VARCHAR DATA_ENGLISH len 0; FOR_NAME: DATA_VARCHAR DATA_ENGLISH len 0; REF_NAME: DATA_VARCHAR DATA_ENGLISH len 0; N_COLS: DATA_INT len 4; DB_ROW_ID: DATA_SYS prtype 256 len 6; DB_TRX_ID: DATA_SYS prtype 257 len 6; INDEX: name ID_IND, id 0 11, fields 1/6, uniq 1, type 3 root page 46, appr.key vals 1, leaf pages 1, size pages 1 FIELDS: ID DB_TRX_ID DB_ROLL_PTR FOR_NAME REF_NAME N_COLS How to repeat: See above.
