I used it ~8 years ago and remember observing that it introduced a huge skew when I gave it control points, but when I restricted the warping to a linear fit it worked enough for my purposes. Apparently well-enough that I didn't think to file a bug report.
I notice that doing 'grep warp t/* ' in the PDL source directory returns nothing.
