I saw new test failures in the test matrix under Darwin/Marshall-UBSAN 
but I don't see them now.  It's totally believable to me that there is 
some undefined behavior in the serialization library implementation.  In 
fact, it may well be that the serialization library cannot perform all 
it's functionality or pass all it's tests without using undefined 
behavior.  Of course this would raise a number of interesting questions 
but first I want to spend some time looking at this.  I don't have time 
right now but I will get to it.  I have one other subtle pending issue 
to resolve.  Neither of these are "quick fixes" that one can just 
implement with some serious thought.
