[GRASS-dev] can't get NVIZ to run

[William Kyngesburye]

I've never had much of a need for NVIZ, though I've been meaning to  
look at it someday.  I occassionally fire it up to try, or just to  
see if it runs.  Every time I try to start it up recently I have  
problems, and possibly I've always had this problem in earlier  
versions of GRASS.

Right now: Mac OS X 10.4.6 Intel and PPC, GCC 4.0.1, GRASS 6.1 CVS  
06-6-24 snapshot.  It's my own build, not Lorenzo's binaries.  TclTk  
8.4.13, it IS an X11 build.  GRASS built with X, opengl, but without  
glw and motif (those shouldn't affect nviz).  I think Lorenzo has  
NVIZ working, so I'm not sure if it's a bug yet (and different from a  
few other crashing nviz bugs already reported), or just that I'm  
doing something wrong (in build or run stage).

I'm trying this with the spearfish6 sample.  I run nviz& from the  
cmdline, and I get the setup window.  I select a raster for elevation  
(elevation.10m) and run it.  It shows progress in the output tab:

Loading Data
Update elev null mask
Loading Data
translating colors from fp

then crashes.  The crash log has this for the crashed thread:

Any ideas?
