[Bug c++/18470] New: [4.0 regression] array bound rejected as non-constant in template

[reichelt at gcc dot gnu dot org]

The following valid code snippet is rejected by mainline:

========================================
template<typename> struct A
{
    static const int i=1;
};

template<typename T> struct B : A<T>
{
    using A<T>::i;
    char s[i];       // fails
    char t[A<T>::i]; // compiles
};
========================================

bug.cc:9: error: array bound is not an integer constant

Mark, I suspect your patch for PR 18429 is responsible for the regression.
Could you please have a look?
