Description:
SET NAMES causes problems for C/ODBC 5.1, because it causes the client library to lose
track of what the client character set is, and the driver expects character_set_results
to be NULL.

How to repeat:
Issue SET NAMES as a query, or use it as the initial statement.

Suggested fix:
Disallow SET NAMES within the driver.

this was committed and will be in 5.1.1.

A note has been added to the 5.1.1 changelog: 

The SET NAMES statement has been disabled because it causes problems in the ODBC driver
when determining the current client character set.
