Sepideh and Mohammad have already let Mark Callabreta know that WCSLIB 7.11 fails when calculating specific coordinates. He has fixed it in WCSLIB 7.12, and in the changelog pointed out:

>  - In wcsp2s() and wcss2p(), fixed handling of status returns from
>    linp2x() and linx2p() relating to distortion functions, specifically
>    with respect to setting the stat[] vector.  Reported by Sepideh
>    Eskandarlou (via Mohammad Akhlaghi).

That is why we have put a warning in Warp's documentation about this and encouraged users to install at least WCSLIB 7.12. However, some might simply miss this important warning. Hence, we should check user's WCSLIB version while running warp, and print a warning to prevent bad results.
