--- Comment #1 from Fariborz Jahanian <fjahanian at apple.com> ---
Here is a related test case which crashes with -fms-extensions.

I am not sure what the treatment should be. Two possibilities:
1) Issue error when used in sizeof.
2) Just like c/c++'s undefined struct ignore it when used in sizeof.

struct anon_fault {
    struct undefined;
};

int main()
{
  return sizeof(struct anon_fault);
}
