--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
ICE started with r197248, before that it has been rejected with
pr70572.C: In function ‘int foo()’:
pr70572.C:3:4: error: expected primary-expression before ‘decltype’
    decltype (auto) a = foo;
    ^
pr70572.C:3:4: error: expected ‘;’ before ‘decltype’
