[boost] Re: aligned_storage not a POD?

boost::aligned_storage is supposed to be an implementation of TR1 aligned_storage, which yields a POD. I even see a specialization of is_pod for aligned_storage in the header. However the class itself (::type only echoes its type back) does not seem a POD at all. It has a default constructor, destructor, a private copy constructor and whatnot. aligned_storage_test does not test its PODness, it only looks at is_pod.

Wow, that is embarassing!

I think that a reasonable test for PODness would be to try to initialize with = {} (if nonscalar) and/or use it in a union.

Good idea. Who is responsible for this code? -- Dave Abrahams Boost Consulting www.boost-consulting.com
