   I never would have guessed that the unreachable() function would get executed in that example. Probably not something you’d encounter in practice, though I have seen some weird things happen with layers of #ifdef

      it's actually probably the most common footgun you'll encounter in practice: non-void functions with no return statements just keep executing past their end. ask me how i know.

      compile with -Wreturn-type if you want to avoid such things...

         Isn't -Wreturn-type enabled by default in both gcc and clang atleast for c++?

            probably - i guess then i meant -Werror=return-type
