           Summary: [c++1y] ICE with pointer to function with auto
                    parameter
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED

The following invalid code snippet (compiled with "-std=c++1y")
triggers an ICE on trunk:

==================================
struct A {};

void (*A::p)(auto) = 0;
==================================

bug.cc:3:18: error: 'void (* A::p)(auto:1)' is not a static member of 'struct
A'
 void (*A::p)(auto) = 0;
                  ^
bug.cc:3:18: error: template definition of non-template 'void (* A::p)(auto:1)'
