WOW!

This is a really bad bug...

mysql> SHOW INDEX FROM LITERAL;

+---------+------------+----------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+

| Table   | Non_unique | Key_name | Seq_in_index | Column_name | Collation | 
Cardinality | Sub_part | Packed | Null | Index_type | Comment |

+---------+------------+----------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+

| LITERAL |          0 | PRIMARY  |            1 | ID          | A         |    
14331755 |     NULL | NULL   |      | BTREE      |         |

| LITERAL |          0 | VALUE    |            1 | VALUE       | A         |    
14331755 |     NULL | NULL   |      | BTREE      |         |

+---------+------------+----------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+

Notice the unique index on VALUE ?

Now take a look at this:

mysql> SELECT *, MD5(LITERAL.VALUE) AS MD5_VALUE FROM LITERAL WHERE ID=567344 
OR ID=14076840;

+----------+-------+----------------------------------+

| ID       | VALUE | MD5_VALUE                        |

+----------+-------+----------------------------------+

|   567344 | Law   | 81588d326cebe6416d3904db93603af1 |

| 14076840 | Law   | 81588d326cebe6416d3904db93603af1 |

+----------+-------+----------------------------------+

Seems like a fatal bug to me!
