Here is another example which works:
int PyObject_IsTrue();
struct object_base
{
    void ptr() const;
};
struct object : public object_base
{
  void ptr1() const;
  typedef void (object::*bool_type)() const;
  inline operator bool_type() const { return PyObject_IsTrue() ? &object_base::ptr : 
&object::ptr1; }
};
void f();
void g (void)
{
    for (unsigned n = 0; n < 100; ++n)
    {
        object kv;
        if (kv)
          f();
    }
}

And another which does not:
int PyObject_IsTrue();
struct object_base
{
    void ptr() const;
  void ptr1() const;
};
struct object : public object_base
{
  typedef void (object::*bool_type)() const;
  inline operator bool_type() const { return PyObject_IsTrue() ? &object_base::ptr : 
&object::ptr1; }
};
void f();
void g (void)
{
    for (unsigned n = 0; n < 100; ++n)
    {
        object kv;
        if (kv)
          f();
    }
}
