--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
ICEs starting with r208426, before that we rejected it with:
pr84661.C:3:36: error: expected primary-expression before ‘auto’
void foo (decltype(((a = 0) || ((auto)))));
^
pr84661.C:3:36: error: expected ‘)’ before ‘auto’
pr84661.C:3:45: error: expected ‘)’ before ‘;’ token
void foo (decltype(((a = 0) || ((auto)))));

I guess this is a dup of PR84642 and PR84647 though.
