I'm using 1.33.1. If I use serialization/shared_ptr_132.hpp, same issue. Does the test fail for you?

RE: [Boost-users] [serialization] Assertion`new_cid==cid'failed-fails on gcc, works on msvcHmm - I'm not sure which version of boost you're using.

For boost version 1.32 one needs to use 

BOOST_SHARED_POINTER_EXPORT(T)

This requirement was eliminated in 1.33 onward but I'm not sure which version you're using

  Nope, same thing. Is there a way to enable some debug traces of the serialization? Inspection by debugging isn't helping much. What does the serialization library do differently for abstract classes? The part that is still confusing me is that I only have these issues when serializing shared_ptr. Raw pointers work just fine.

  OK

  Try the following:

  //BOOST_CLASS_EXPORT(base);

  BOOST_CLASS_EXPORT(derived);

  #include <boost/serialization/shared_ptr.hpp>

  //BOOST_SERIALIZATION_SHARED_PTR(base);

  BOOST_SERIALIZATION_SHARED_PTR(derived);

  The base class shouldn't need exporting as it never

  directly instantiated.
