Comment (by cmbarton):

 This is happening with Spearfish and with the new NC dataset. I've simply
 set my region to match the elevation DEM. In the NC dataset, I think this
 is a little over 2million cells. This is not extraordinarily large and it
 IS the demo set for GRASS.

 It is with 10.4 AND with 10.5 for everything except r.random. This is only
 with 10.5.

 I'm also finding that r.resamp.interp says it makes maps, but it does not.
 With the neighbors algorithm, it makes a map that is exactly the raster
 points that are input. That is, there is no interpolation. For bilinear
 and bicubic, it makes NAN maps. I've checked this with r.info. I'll give
 examples below. Note that the output of the nearest routine produces only
 500 points (see r.univar results)--the same number I used as points for
 interpolation. Also note that I just updated from the SVN trunk, did a
 make distclean, and compiled fresh this afternoon.
