This code fails to compile on Comeau C++ and VC++ 7.1 (with language
extensions disabled)
template <class T>
struct B
{
T b;
};
template <class T>
struct D : B<T>
{
void f() { b = 1; }
};
int main()
{
D<int> x;
x.f();
}
Error messages refer to 'b = 1;' with the message 'undefined identifier b'.
Substituting this->b for b or making B a non-template class both make the
code compile.
What's going on here? I was so surprised when I saw this on VC++ that I
assumed it was a compiler bug, but apparently not.
