Call the following snippet `bug.cc':
struct a {
static const int size = 0;
};
template <typename T>
struct p {
int a[T::size]; // Here it says "error: creating array with size zero (`0')"
};
p<a> n;
template <typename T>
struct q {
int a[0]; // Here it says nothing!
};
q<a> m;
$ g++ -v

Should I report this as a bug?
If so, which kind of bug is it?
All the best,
