gdalinfo -hist reports negative counts

Reported by: peifer Owned by: warmerdam
Priority: normal Milestone: 2.0.0
Component: Utilities Version: svn-trunk
Severity: normal Keywords:


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.

Yes, provided that this gets incorporated in GDAL 2.0 ...
