Good question.  According to 12.4/3 it is non-trivial.  But according to 
17.3.2.2/1 it would have the same semantics as an implementation that 
provided the trivial (compiler-generated) version.

At this point we probably get into word games...

Bottom line is ~pair<int, int> doesn't (or shouldn't) do anything, no 
matter how it is implemented.
