Sounds like you want type_with_alignment<T>::type storage; new ((void*)&storage) T(x, y, z) Can you really do anything to make this cleaner? I guess: aligned_storage<T> storage; new (storage.bytes) T(x, y, z); might be a help. What else are you gaining? And how do you destroy the T? If not explicitly and you don't have a "constructed" flag, you're going to have exception-safety problems. -- Dave Abrahams Boost Consulting www.boost-consulting.com _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
