--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I guess it is not a big deal to do:
   save_growing_size = obstack_object_size (&obstack);
+  save_growing_value = NULL;
   if (save_growing_size > 0)
     save_growing_value = obstack_finish (&obstack);
to workaround the bogus warning.
Of course it would be nice to understand why uninit doesn't handle this, since
it should be the pretty much easiest case of predicated uninit analysis.
