De la part de Pfligersdorffer, Christian

We were facing similar problems jumping from 1.36 to 1.45. Binary archive backwards compatibility is broken in a few places.

But: it is fixable. We may provide a patch

Thanks Christian for your reply to this annoying issue. If you confirm that the backward compatibility is broken for Boost.Serialization #1.40 to #1.47 then *Yes* I would really appreciate any king of patch to address this issue. Looking the Boost.Serialization code, my first feeling would be to patch the implementation of basic_binary_iarchive::load_override(class_id_type & t, int version) for the library_version_type(5) ('5' stands for the library version for the release #1.40) but maybe this patch is too naïve and insufficient. If you can send me back a patch for this issue, I'll use it ASAP.

is there a TRAK ticket?

I'm not sure but the ticket #5567 (https://svn.boost.org/trac/boost/ticket/5567) seems to address this bug. Thanks in advance and best regards, Marc Viala
