# BUG#13825 "Triggers: crash if release savepoint".
# Also general test for handling of savepoints in stored routines.
#
# According to SQL standard we should establish new savepoint
# level before executing stored function/trigger and destroy 
# this savepoint level after execution. Stored procedures by
# default should be executed using the same savepoint level
# as their caller (to execute stored procedure using new 
# savepoint level one should explicitly specify NEW SAVEPOINT
# LEVEL clause in procedure creation statement which MySQL
