Comment(by mwtoews):

 This function seems to get the correct answers:
 http://geographiclib.sourceforge.net/html/C/geodesic_8h.html#a19bc3d000428010ad9d8509174e672c9

 Perhaps I'll investigate further to see what's ticking underneath in
 GeographicLib, and see what happens if I rewrite spheroid_direction and
 spheroid_distance functions in lwspheroid.c
