--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Well volatile void * is a pointer to volatile void and the pointer itself does
not have the volatile on it.

I think the only real issue here is the error message.  IIRC allocators do not
(and cannot) support volatile qualified types.
