Huh? This is *extremely* confusing. A SHOW CREATE TABLE after a DROP
TABLE is expected to fail with "no such table".

Please add an --echo # comment in the test file saying that you copy t1
from std_data, before using it. That way the result file would become
somewhat readable.

As mentioned above, please use --echo # here. E.g.

--echo # Test with an existing table which is corrupted
--echo # Copy t1 from std_data.

An increasing number of developers does even use --echo # for the
introductory comment:

--echo #
--echo # Bug#...
--echo #

Please decide yourself, if you want to jump on that train.
