--- Comment #3 from Paul Thomas <pault at gcc dot gnu.org> ---
I am trying to fix this at source.

However,

   subroutine unlimited_rebar (arg)
-    class(*) :: arg(:)
+    class(*), allocatable :: arg(:)              ! Not having this allocatable
=> pr117901
     call class_bar (arg)
   end


removes the problem. If I don't get to the source by the end of the day, I will
apply the patch as a temporary measure.
