Description (last modified by )
gdalwarp is generating output that has large black rectangles that should not be there when given a large input file (a bluemarble octant). The rectangles move around depending on the output file format and depending on the value passed to the "-wm" option. If I use "-wm 1024" or greater the problem goes away (the input file is 1.3GB). The warp command I am using is:
gdalwarp -rn -te -4000000 -3000000 0 3000000 \ -t_srs '+proj=gnom +lon_0=-90.0 +lat_0=58 +a=5500000 +b=5500000' \ -tr 2000 2000 -co 'TILED=YES' zz-src.tif zz.tif
The same error happens with other projections, and without the TILED=YES option. Valgrind doesn't report any errors.
I've attached a small thumbnail showing what it looks like.

Can you provide a gdalinfo report for the input file so I can try and construct something structurally similar to test?
