I should have caught up on my mail before I dove back into looking at test
results. I'd just discovered what you say about an hour ago and have been
debugging the test to see if I could see where it should logically be
different. I'm not even sure I know what lower_, upper_, and size_ are
supposed to be for, or where/when things get allocated (if they do) when
one accesses something outside the current bounds.
