Apply the correct pattern for debug instrumentation: SET @save_dbug=@@debug_dbug; SET debug_dbug='+d,...'; ... SET debug_dbug=@save_dbug; Numerous tests use statements of the form SET debug_dbug='-d,...'; which will inadvertently enable all DBUG tracing output, causing unnecessary waste of resources.

# 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.
