Description
I used gdalinfo -hist on a byte-type GeoTIFF with 65000 x 46000 pixel.
The count for value 0 is: -1652904589.
The correct count is actually 2642062707 (as given by GRASS r.stats). This looks pretty much like an integer overflow.

Thanks for taking care. So in the meantime we'll just wait for GDAL version 2, correct?
