| 5 | // This reproduces a crash that occurred when multiple shared libraries were |

| 6 | // using Boost.Serialization built statically. That causes core singletons to be |
|---|
| 7 | // instantiated in each shared library separately. Due to some destruction order |
|---|
| 8 | // mixup in the context of shared libraries on linux it is possible, that |
|---|
| 9 | // singletons accessed in destructors of other singletons are already destructed. |
|---|
| 10 | // Accessing them will then lead to a crash or memory corruption. |
|---|
| 11 | // For this we need 2 shared libraries, linked against static boost. They need to |
|---|
| 12 | // instantiate extended_type_info_typeid with different types, either by serializing |
|---|
| 13 | // 2 types (which will do that internally) or by accessing the singletons directly. |
