In that case we have clearly a defect in the standard, because std::array
doesn't dynamically allocate memory and in general you can't play tricks with
pointers, it all comes down to this.

Benjamin, we all know that traditionally basic_string can be instantiated only
for PODs, per 21/1. Certainly a POD can't throw. For the C++0x basic_string
there are some news in this area, still I'm pretty sure there are no changes in
this area.
