// test_multi_shared_lib.cpp: test that implementation of extented_type_info

// works when using multiple shared libraries

// This reproduces a crash that occurred when multiple shared libraries were

// using Boost.Serialization built statically. That causes core singletons to be

// instantiated in each shared library separately. Due to some destruction order

// mixup in the context of shared libraries on linux it is possible, that

// singletons accessed in destructors of other singletons are already destructed.

// Accessing them will then lead to a crash or memory corruption.

// For this we need 2 shared libraries, linked against static boost. They need to

// instantiate extended_type_info_typeid with different types, either by serializing

// 2 types (which will do that internally) or by accessing the singletons directly.

// Use, modification and distribution is subject to the Boost Software

// License, Version 1.0. (See accompanying file LICENSE_1_0.txt or copy at

// http://www.boost.org/LICENSE_1_0.txt)

#include <boost/serialization/config.hpp>

// Both shall instantiate different(!) singletons and return true
