[Bug c/39748] [4.5 regression] warning "outside bounds of constant string" not suppressed in dead code

The problem comes from some convoluted code that was apparently substituted for
strlen to special-case constant arguments. It boils down to:

int f(void) {
  if (0)
    return ((const char *) "")[2];
  return 0;
}

(without the cast, no warning is given).
