[Bug c++/24671] New: [4.0/4.1 regression] ICE with zero-sized arrays

[reichelt at gcc dot gnu dot org]

The following testcase causes an ICE:

==============================================
template<typename> struct A
{
    typedef int X;
    static const int i = 0;
};

template<typename> struct B
{
    typedef typename A<char[A<B>::i]>::X Y;
    template<typename T> B(T, Y);
};

B<int> b(0,0);
==============================================

dPR19208B.cc:10: internal compiler error: in push_access_scope, at cp/pt.c:176
Please submit a full bug report, [etc.]

The testcase crashed since at least gcc 2.95.3, but was fixed with the
patch for PR19208. The problem reappeared on the 3.4 branch and mainline
with Josh's patch for PR 19989.

I think the code should be accepted at least with -fpermissive,
but rejected with -pedantic.
