Good find!

I think I would do it slightly different, the patch fixes the symptom
correctly by allocating new objects, but the underlying cause to me
seems that the original intention was to transfer the pointers (hence
the method's name) but that somehow got mangled with the transition from
old List to ::std::vector

Instead of creating copies I'd do

-      rList.reset();
+      rList.clear();

Please check if that fixes the problem.
