Any one else replicating this error?

bizarre. @cbeall3 ?

[Andrew Melim]

@nsrinivasan7 since you also run windows, can you verify this issue isn't isolated to me?

[Chris Beall]

I had this issue on Windows, too.

Fixed this issue by specifying function pointer overloads before passing the function pointer to the Expression

Point3_ transform_to(const Pose3_& x, const Point3_& p) {

  Point3(Pose3::*transform)(const Point3& p, 
                           boost::optional<Matrix36&> Dpose,
                           boost::optional<Matrix3&> Dpoint) const = &Pose3::transform_to;

  return Point3_(x, transform, p);
}
