CREATE TABLE test.t1( a INT );

# What we need to create here is a bit of a corner case:

# We need a star query with information_schema tables, where the first

# branch of the star join produces zero rows, so that reading of the 

# second branch never happens. At the same time we have to make sure

# that data for at least the last table is swapped from MEMORY/HEAP to 

# MyISAM. This and only this triggers the bug.
