// 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.
