- // 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.
