Re: [Boost-users] [serialization]Assertion`new_cid==cid'failed-fails on gcc, works on msvc

Currently I only have the HEAD and RC_1_34 on my system and can't run a gcc test. I did build and compile and test with vc 7.1 and found no problems. Try serializing your test to xml archive. That will make the details a lot more visible. Sohail Somani wrote:

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

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(base);

BOOST_SERIALIZATION_SHARED_PTR(derived);

The base class shouldn't need exporting as it never

directly instantiated.

bit of gymnastics. Check out the "test_shared_ptr" and the source of serialization/shared_ptr.hpp

I think I've followed the documentation, but the attached test still triggers an assertion when deserializing on gcc 3.2.2:

$ ./build/stage/bin/test_serialize Serialized form: 22 serialization::archive 3 0 1 2 7 derived 1 0 0 1 0 1 10 derived id test_serialize: basic_iarchive.cpp:466: const boost::archive::detail::basic_pointer_iserializer*

...

...

detail::basic_iarchive&, void*&, const boost::archive::detail::basic_pointer_iserializer*, const boost::archive::detail::basic_pointer_iserializer*(*)(const boost::serialization::extended_type_info&)): Assertion `new_cid == cid' failed. Aborted

This assertion does not trigger occur on Visual C++ 7.1. Can you spot if I'm doing something obviously silly?
