I also posted on the list about this and other related problems but Robert has not responded yet... On Fri, Apr 1, 2011 at 2:54 PM, Brandon Kohn <blkohn@hotmail.com> wrote:

Hello,

I've been using Boost.Serialization for some time, and have found a break while upgrading to 1.46.1 (from 1.37). The problem seems to be the size of the integral type which stores

v. 1.37 has:

BOOST_ARCHIVE_VERSION(){ return 5; }

When saving to the binary_oarchive:

// basic_binary_oarchive.hpp void save_override(const class_id_type & t, int){ // upto 32K classes const int_least16_t x = t.t; * this->This() << x; }

1.46.1 has:

void load_override(class_id_type & t, int version){ library_version_type lvt = this->get_library_version(); if(boost::archive::library_version_type(7) < lvt){ this->detail_common_iarchive::load_override(t, version); } else if(boost::archive::library_version_type(6) < lvt){ int_least16_t x=0; * this->This() >> x; t = boost::archive::class_id_type(x); } else{ int x=0; * this->This() >> x; t = boost::archive::class_id_type(x); } }

The salient point is that on the load in 1.46.1 an int is used to read the value which was stored as int_least16_t in version 5 archives. The trunk seems to have this as well.
