Reduced it down to this -- compiles with clang w/o the patch, but fails with it.

  __attribute__((device)) double copysign(double, double);
  __attribute__((device)) double copysign(float, double);
  template <typename> struct a { static const bool b = true; };
  template <bool, class> struct c;
  template <class f> struct c<true, f> { typedef f g; };
  template <typename d, typename h>
  __attribute__((device)) typename c<a<h>::b, double>::g copysign(d, h) {
    double e = copysign(0, e);
  }
