well, we havn't had it lately.

But this is actually a little different since this is calling a member
function inside serialization. Since save(...) is a const member
funtion, the f() would have to be const. if you can't make f()
const, you've got something to look into.

FYI, the more resent versions of the library implement the
trap where by non-const are serialized as BOOST_STATIC_WARNING
so that you're program will compile and run but emit
this "disclaimer" indicating that my view is that this is really
a bad idea. You're free to ignore the warning whereas
before you couldn't.
