compare_ctlpts()

static void compare_ctlpts ( Point const  est_b[], Point const  exp_est_b[]  )

static

Determine whether the found control points are the same as previously found on some developer's machine.

Doesn't call utest__fail, just writes a message to stdout for diagnostic purposes: the most important test is that the root-mean-square of errors in the estimation are low rather than that the control points found are the same.
