# BUG#15737: Stored procedure optimizer bug with LEAVE
#
# This is a much more extensive test case than is strictly needed,
# but it was kept as is for two reasons:
# - The bug occurs under some quite special circumstances, so it
# wasn't trivial to create a smaller test,
# - There's some value in having another more complex code sample
# in this test file. This might catch future code generation bugs
# that doesn't show in behaviour in any obvious way.
