# Bug #27417  	thd->no_trans_update.stmt lost value inside of SF-exec-stack
# bug #28960    non-trans temp table changes with insert .. select
#               not binlogged after rollback
#
# testing appearence of insert into temp_table in binlog.
# There are two branches of execution that require different setup.

# checking binlog content filled with row-based events due to
# a used stored function modifies non-transactional table
