A recent change in SVN head (whether directly to shared_ptr or something else I'm not sure) has broken some of the TR1 tests: http://beta.boost.org/development/tests/trunk/developer/output/daw-msvc71-bo... The two patches below would fix this, but as ever I'm open to other/better suggestions. Cheers, John.
