Confirmed.

Reduced testcase (-O2 -ftree-vectorize -march=pentium4):

=========================================================
struct A
{
  int a[4];
  int& operator[](int i) { return a[i]; }
};

struct B : public A
{
  int& operator[](int i) { return A::operator[](i); }
};

void foo(B &b)
{
  for (int i=0; i<4; ++i)
    b[i] = 0;
}
=========================================================
