It would be pretty nice if there was at least one sentence here as to why this change is needed and/or wanted. Repeating only what goes into the ChangeLog is not very useful. Fundamentally my question is: Isn't -O0 the default anyway? Why would it be necessary to specify this on the command line of any test case? Jan
