I dont have the knowledge of the inner coding of the archives... but as far as I understood the issue come from theses lines :
if(3 < ar.get_library_version()) ar >> BOOST_SERIALIZATION_NVP(item_version);
in the vector.hpp header file (load method)
would it be possible to surround these lines with a try catch block in a way like this :
try { if(3 < ar.get_library_version()) ar >> BOOST_SERIALIZATION_NVP(item_version); } catch(...) { do something to reset the state of the archive before the ar >> BOOST_SERIALIZATION_NVP(item_version); attempt }
Is it something possible or am i just a dreamer ? would it have some performance impact ? In such a case maybe it could be a choice to have a full compatible library with an #ifdef code selection mechanism...
I hope this proposal is not too ridiculous....
This might or might not throw an exception, and the exception might be thrown somewhere farther along deserialization. Matthias
