# 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.
