[Boost-users] serialization of derived classes...

Hi list,

I'm using the boost::serialization lib to archive
classes in a VC7.1 program.
I have a class C, derived from B, derived from
(abstract) A

now, in serialisation of C, I did:
ar &  boost::serialization::make_nvp( "baseobject",
boost::serialization::base_object<B>( t ) );

This seems to give a memory leak on closing the
application.

So I tried the following 2 lines:
ar &  boost::serialization::make_nvp( "baseobject",
boost::serialization::base_object<A>( t ) );
ar &  boost::serialization::make_nvp( "baseobject2",
boost::serialization::base_object<B>( t ) );

and this seemed to work....

What is the correct way of saving C (derived from  B
which is derived from A)?
It seems a bit strange to me that i have to call
serialization of A in the ser. of C. Shouldn't B take
care of this?

thanks,
Filip Peters
