LWG 834 is about comparing unique_ptr<T,D>::pointer to nullptr_t LWG 1307 is about missing != comparisons for other types. Neither is related to this issue, and I don't know of any thread on this topic. The code would work if there was: template<class T1, class D1> bool operator!=(const unique_ptr<T1, D1>& x, const nullptr_t&); (along with a version with the arguments reversed, and similarly for operator==) But there is no such function in the WP. Nor is there a member unique_ptr::operator!=(nullptr_t) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42925
