--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Hardly a regression - 4.8.5 which doesn't ICE doesn't grok auto params:
t.C: In function ‘auto foo(bool)’:
t.C:9:24: error: parameter declared ‘auto’
auto f = [](auto c) -> B<decltype(c)::call(b)> { };
^
t.C:9:32: error: decltype evaluates to ‘<type error>’, which is not a class or
enumeration type
auto f = [](auto c) -> B<decltype(c)::call(b)> { };
^
...
ICEs since 4.9.0.
