[gdal-dev] gdal2tiles crashes on some rasters

[Alexander Bruy]

Hi all,

I have troubles using gdal2tiles. When I try to generate tiles from raster
it fails with error

Generating Base Tiles:
ERROR 5: Illegal values for buffer size
ERROR 5: Illegal values for buffer size
Traceback (most recent call last):
  File "/usr/bin/gdal2tiles.py", line 2241, in <module>
    gdal2tiles.process()

Here is my command
gdal2tiles.py -z '8-14' --srcnodata=0 merc_SHL_tmv.tif ./output

gdalinfo reports that raster georeferenced

Coordinate System is:
PROJCS["WGS 84 / UTM zone 54N",

    PARAMETER["false_northing",0],
    UNIT["metre",1,
        AUTHORITY["EPSG","9001"]],
    AUTHORITY["EPSG","32654"]]

When I set input CRS in gdal2tiles command and try again same error appears.
Also I try to warp input raster to Google Mercator using this command

gdalwarp -t_srs '+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0
+lon_0=0.0 +x_0=0.0
+y_0=0 +k=1.0 +units=m +nadgrids=@null +wktext  +no_defs' SHL_tmv.tif
merc_SHL_tmv.tif

and generate tiles from reprojected image. Same result.
But for some other raster after reprojecting with same command gdal2tiles works.
Any ideas what is wrong?

Thanks
