Turning off pointer tracking IS questionable if one is serializing through 
ponters!
why not just leave it on?

consider the following alternatives

a) understand why the warning is there and ignore it on purpose.
Include comments in the source code of your app explaining your
decision

b) enable pointer tracking

c) consider different type of polymorphism - e.g. Boost.Variant
which is supported by Boost.Serialzation out of the box

d) experiment with serialziation via a base class reference.  I
don't remember of Boost.Serialization has the smarts to
stay ahead of the programmer in this case.
