[Bug c++/17323] [3.4/4.0 regression] ICE on invalid code if static member array initialized with size computed as division by zero

Here's a reduced testcase without sizeof:

=================================
template<int N> struct A
{
    static const int i = 8/N;
    char c[i];
};

A<0> a;
=================================

The error message is:

mmm.cc: In instantiation of 'A<0>':
mmm.cc:7:   instantiated from here
mmm.cc:3: warning: division by zero in '8 / 0'
g++: Internal error: Segmentation fault (program cc1plus)

The ICE appears with 3.4.0. Before I get the following error message:

mmm.cc: In instantiation of `A<0>':
mmm.cc:7:   instantiated from here
mmm.cc:3: warning: division by zero in `8 / 0'
mmm.cc:7: error: variable-size type declared outside of any function
mmm.cc:7: error: variable-size type declared outside of any function
