Description of problem: See upstream bug : http://trac.osgeo.org/gdal/ticket/3458 This is a serious regression introduced during 1.7 development, that will affect warping any sufficiently large image. Wasn't detected by our autotest suite because the test image were small enough, but this will trigger easily with real-life images. I'd strongly advise to apply at least http://trac.osgeo.org/gdal/changeset/19010 It would be also good to apply : http://trac.osgeo.org/gdal/changeset/19014
For the record GDAL 1.7.2 has been released, which includes the above mentionned fixes
1.7.2 is now in rawhide
