# Bug #15205 Select from CSV table without the datafile causes crash
#
# NOTE: the bug is not deterministic
# The crash happens because the necessary cleanup after an error wasn't
# performed. Namely, the table share, inserted in the hash during table
# open, was not deleted from hash. At the same time the share was freed
# when an error was encountered. Thus, subsequent access to the hash
# resulted in scanning through deleted memory and we were geting a crash.
# that's why we need two tables in the bugtest
