I don't think there is a destructor to call in this case as the type is trivial, so I didn't think that it was semantically correct to call the dtor in this case, unless you think it's appropriate even for the trivial case (although I'd be happy to try that if that's your preference). The destructor for the `_Trait::_Available` case below does call the underlying object's destructor, and MSAN understands that.
