[GRASS-dev] winGRASS OSGeo4W crashes when switching to 3D view

[Markus Neteler]

Hi,

while teaching our IRSAE course
(http://gis.cri.fmach.it/grass-gis-and-r-course/) we did not have
success to perform a NVIZ exercise on Windows.

Switching to 3D mode leads to a GUI crash when loading the "elevation"
DEM. We used "elevation" in the new (yet to be improved) Piemont
location [1].
No error message shown, just crash.

If anyone wants to test:

wget http://geodati.fmach.it/gfoss_geodata/grassdata_course_version1.7z

# unpack (7a is contained eg in p7zip-plugins package):
7z x grassdata_course_version1.7z

--> grassdata_piemonte/user1

Note: It is a new issue since 7.0.1, in 7.0.0 which is installed on
the same machine no such issue.

I suspect that it is the elevation map size causing the issue since
the DEM is larger than that of the NC dataset.
