This would be a pointer to a primitive. Correct serialization of a pointer

requires that all pointers to a type be tracked. No one would want to

do this for all integers in the program. If you really want to serialize

a pointer to a primitive type - like an int - use BOOST_SERIALIZATION_STRONGTYPEDEF

to make a distinct type equivalent to an int which is not in fact an int.

Review the manual regarding serialization of pointers which has

some subtle aspects.
