Category: serialization Group: None Status: Open Resolution: None Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Robert Ramey (ramey) Summary: crash deserializing 1.32 data (poly archive + stl container) Initial Comment: Hello, i got a problem deserializing STL containers with polymorphic archive interfaces. Serialization/Deserialization with boost 1.32 works fine. Simple object trees with stl containers (maps) and base class registration (no shared_ptr used). When i deserialize the data (xml) with boost 1.33 it asserts/crashes in basic_iarchive.cpp ( basic_iarchive_impl::reset_object_address): --- snip ---- inline void basic_iarchive_impl::reset_object_address( const void * new_address, const void *old_address ){ // if the this object wasn't tracked std::size_t i = moveable_object_position; if(i >= moveable_object_stack.size()) return; if(old_address != object_id_vector[i].address) // skip to any lower level ones ++i; while(i < moveable_object_stack.size()){ // calculate displacement from this level assert(object_id_vector[i].address >= old_address); <---- assert here !!! // warning - pointer arithmetic on void * is in herently non-portable // but expected to work on all platforms in current usage std::size_t member_displacement = reinterpret_cast<std::size_t>(object_id_vector[i].address) - reinterpret_cast<std::size_t>(old_address); ---- snip ---- Callstack:

---- The serializing code is implemented using split members and manual registration and usually read like this: ---- snip --- void DerivedLayoutObject::serialize( boost::archive::polymorphic_oarchive& ar, const unsigned int /* version */) { // register pointer type info ar.register_type(static_cast<LayoutObject*>(0)); // serialize data members ar & boost::serialization::make_nvp( "status", m_status); .... // serialize stl container (std::map here) ar & boost::serialization::make_nvp( "childs", m_childs); } (deserialization vise-versa) --------------------- Whats the problem here? I simply rebuilt the whole project using 1.33. Regards, A.
