--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed for the missing diagnostic.  I'm not sure we should count this as
regression for the sefault - eventually the new behavior should be documented
in porting_to.html or changes.html and maybe a -fallow-null-references
compatibility option can be added (well, quite late now).
