+// 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.
