problems finding maximum convexity

I am having problems finding a routine that will find the points of
maximum convexity on a detailed DEM.  I am using GRASS 4.1.5 running on
Linux (2.0.29).  

If I run r.param.scale, it seems to calculate everything and then give
me a segmentation fault error.

If I run, it ignores most of my data points saying "ignored
2768 points - outside region."  However, if I use d.sites, it is clear
that my data points are in my region.  

What am I doing wrong?  Is there something I can fix, or is this simply
the nature of the beast?
