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.
