IMO, it is unreasonable to expect C++ to work with RTLD_LOCAL unless the object so loaded is indeed self-contained (which precludes linking against a common shared library, as in this case). Too many aspects of the language depend on being able to merge duplicates coming from different sources. In this case, the problem comes from std::type_info; the runtime library expects to be able to compare type_info nodes by pointer equivalence. Templates and static variables in inline functions would also have trouble. Jason
