Comment (by martinl):

 Replying to [ticket:163 cmbarton]:
 > Sometime recently, g.transform stopped calculating forward and backward
 error for 2nd order transformations. It simply returns 0's. 1st order
 transformations still work fine AFAICT.

 The 2nd order transformations requires at least 6 GCPs. Your input POINTS
 file contains 6 points. Then forward/reverse error is 0.0's.
