Something's not right with this result (among others): http://www.boost.org/development/tests/develop/developer/output/teeks99-02e-... It says "Rev 906385497d1f3de04bb8391c5af87e563fd4c0f7". Revision 906385 updates config, and the preceding revision that updates smart_ptr is https://github.com/boostorg/boost/commit/891371e4ba8edf7dd21dc828841f5eab567... which brings it up to +Subproject commit e1f170cd494d2e7ce5e6e7d3f0fe016aceb88048 Rev. e1f170 of smart_ptr is a relatively recent one, as can be seen here: https://github.com/boostorg/smart_ptr/commits/develop The error messages in the report, however: C:\local\teeks99-02\e\boost_root\boost/smart_ptr/detail/shared_count.hpp(276) : error C2903: 'rebind' : symbol is neither a class template nor a function template C:\local\teeks99-02\e\boost_root\boost/smart_ptr/make_shared_object.hpp(174) : see reference to function template instantiation 'boost::shared_ptr<int>::shared_ptr<T, ... seem to suggest that neither shared_count.hpp nor make_shared_object.hpp have been updated to e1f170.
