Just look at boost/serialization/string.hpp and do the same thing

Yes, that was my first thought, too. Consider the code below.
Execution fails with this assertion:
a.out: test.cc:47: void load(): Assertion `size == 10' failed.
Aborted
I also tried the collection-based approach which is currently
commented out in serialization/string.hpp, but this does not
compile since basic_string<> does not have a back() method.
