+nondeterministic-pointer-usage
+==============================
+
+Finds nondeterministic usages of pointers in unordered containers.
+
+One canonical example is iteration across a container of pointers.
+
+.. code-block:: c++
+
+ {
+ for (auto i : UnorderedPtrSet)
+ f(i);
+ }
+
+Another such example is sorting a container of pointers.
+
+.. code-block:: c++
+
+ {
+ std::sort(VectorOfPtr.begin(), VectorOfPtr.end());
+ }
+
+Iteration of a containers of pointers may present the order of different
+pointers differently across different runs of a program. In some cases this
+may be acceptable behavior, in others this may be unexpected behavior. This
+check is advisory for this reason.

Thanks @whisperity , I'll look for more candidates here, maybe there's at least
one more candidate to support the creation of an advisory group.
