+----------------------------+---------------------+------+-----+---------------------+-------+
36 rows in set (0.03 sec)

How to repeat:
USE INFORMATION_SCHEMA;
DESC INNODB_TRX;

Suggested fix:
Remove the column duplication.

a side note:
trx_apative_hash_latched should be
trx_adaptive_hash_latched

Passing this to Jimmy, he worked on this and he can best tell how the duplication happened.
