 The ICE is now gone on both 3.3 and 3.4, and the code is rejected. The only
 reason why I keep this PR open is that I'm not sure if the code is legal or
 not. With GCC 2.95, A<> gets instantiated as A<int (B::)()>, which I am not
 sure it's a legal type. Can some GCC extension guru comment on this?
