[Gdal-dev] gdalinfo vs Grass issues

Using todays' GDAL and GRASS CVS, gdal-grass 1.3.1.2.


Problems:

A. gdalinfo -mm reports Min/Max=nan,nan for any Grass raster exported
with r.out.gdal, [1], which is wrong - see [2] for actuall value range.

B. Also using the GDAL Grass driver wrong value is calculated, moreover
gdalinfo issues ERROR 6 twice and segfaults in the end [3].

C. ERROR 6 and segfault on gdalinfo take place for Grass rasters even if
-mm is not used [4].



Backtrace is attached.
