Tests on clang-20/21 had both of these tests overrunning the stack. The check_stack_overrun function checked the function earlier with a 2*STACK_MIN_SIZE margin. The exection within the processing is deeper then when check_stack_overrun was called. Raising STACK_MIN_SIZE to 44k was sufficient (and 40k wasn't oufficient). execution_constants also tested however the topic mention tests are bigger. Perfscheam tests * perfschema.statement_program_nesting_event_check * perfschema.statement_program_nested * perfschema.max_program_zero A small increase to the test thread-stack-size on statement_program_lost_inst allows this test to continue to pass.

# Test case to show the behaviour of stored program instrumentation
|
|
# when values of the system variables performance_schema_max_program_instances &
|
|
# performance_schema_max_statement_stack are less than the statistics collected.
|
|
# The status of the lost instrumentation is shown through the status variables
|
|
# performance_schema_program_lost & performance_schema_nested_statement_lost

|
|
# Restarting the server at the begining of the test.
|
|
# This is to avoid the instrumentation of extra SPs called by MTR
|
|
# These additional stored programs which will be added might cause
|
|
# result content mismatch failure.
