with const-qualified member function
Product: gcc

A file reproducing the bug
With 4.8 it compiles.
With 4.9.0 we got:
main.cpp: In instantiation of ‘struct A<int (C::*)() const>’:
main.cpp:22:8: required from ‘void make(T) [with T = int (C::*)() const]’
main.cpp:27:13: required from here
main.cpp:6:18: attention : invalid application of ‘sizeof’ to a function type
[-Wpointer-arith]
int fail[sizeof(T) - 1000];
^
main.cpp: In function ‘void make(T) [with T = int (C::*)() const]’:
main.cpp:22:8: erreur: size of variable ‘a’ is too large
A<T> a;
^
Because it use the attribute specialization of our template.
