[Bug c++/29020] New: [4.0/4.1/4.2 regression] ICE using A<N>::A instead of A<N> in friend declaration

[reichelt at gcc dot gnu dot org]

The following (IMHO valid) code snippet triggers a segfault since GCC 3.4.0:

==================================================
template<int> struct A
{
    void foo();
};

struct B
{
    template<int N> friend void A<N>::A::foo();
};
==================================================

x1.cc:8: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]

Before the code was accepted.
