I really do not know what to say here. There is a first do no harm principal
here. it does not sound like this is really a bug and i do not think that
mucking with the compiler to make a test on a program that has undefined
behavior is really the right thing to do.
this really is not so much a df question as a question for what kinds of
behavior are we going to consider to be "correct".
