 A colleague ran this test through his g++ 4.3.3 system, and it only
 reported eight warnings - not the required ten.

 I believe it was the "f<A>()" variants that did not warn - which seem to
 align with the check (above) in the serialization code.

 However, this is ultimately a side-issue (even though it may have
 disguised behaviour) and the main issue is that it looks like the
 serialization code for shared_ptr needs to check for polymorphism, and
 route accordingly.  I see there are other places in the serialization code
 that do this with a bit of mpl::eval_if.
