--- Comment #1 from David Binderman <dcb314 at hotmail dot com> ---
Reduced C++ code seems to be:

class a {
public:
  double b() const;
};
class c {
public:
  int m_fn2() const;
};
double a::b() const {
  return 0 == 0 ? reinterpret_cast<const c *>(this)->m_fn2() : 0;
}
bool d;
void e() {
  a f;
  double g = f.b();
  d = __builtin_isnan(g);
}
