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

I'm using 1.33.1. If I use serialization/shared_ptr_132.hpp, same issue. Does the test fail for you? -----Original Message----- From: boost-users-bounces@lists.boost.org on behalf of Robert Ramey Sent: Wed 3/28/2007 1:15 AM To: boost-users@lists.boost.org Subject: Re: [Boost-users][serialization]Assertion`new_cid==cid'failed-fails on gcc,works on msvc 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 Robert Ramey "Sohail Somani" wrote in message news:1C1EBEF8DBACDC439D038EA051674EC73EE10C@xbox.financialcad.com... 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. -----Original Message----- From: boost-users-bounces@lists.boost.org on behalf of Robert Ramey Sent: Tue 3/27/2007 10:28 PM To: boost-users@lists.boost.org Subject: Re: [Boost-users] [serialization] Assertion`new_cid==cid'failed-fails on gcc, works on msvc 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.

Note that serialize a poly morphic shared pointer requires a little 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* boost::archive::detail::basic_iarchive_impl::load_pointer(boost::archive

...

...

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?
