Changing the target to 5.0 only, because 5.1/6.0 are not affected by this bug.

  Fix for bug #34889: mysql_client_test::test_mysql_insert_id test fails 
                      sporadically
  
  Under some circumstances, the mysql_insert_id() value after SELECT ...
  INSERT could return a wrong value. This could happen when the last
  SELECT ... INSERT did not involve an AUTO_INCREMENT column, but the
  value of mysql_insert_id() was changed by some previous statements.
  
  Fixed by checking the value of thd->insert_id_used in
  select_insert::send_eof() and returning 0 for mysql_insert_id() if it
  is not set.

Noted in 5.0.60, 5.1.24, 6.0.5 changelogs.

Under some circumstances, the value of mysql_insert_id() following a
SELECT ... INSERT statement could return an incorrect value. This
could happen when the last SELECT ... INSERT did not involve an 
AUTO_INCREMENT column, but the value of mysql_insert_id() was changed
by some previous statements.
