Well, that sounds largely impossible. Can you point exactly which bug are you talking of? I know for a fact that the extension itself has always worked for basic rvalue usage, with basic types. Instead, I would not be surprised if some more complex usage of it used to be (or still is) broken, like weird lvalue contexts, usage in templates, operator overloading or similar.

Yes this was PR 19068 and bug 18548.
