Can you attach an example file?
What version of gdal are you using?

#2 Updated by anonymous - over 17 years ago

this is a general compression bug in libgdal-1.3.2 and earlier.
gdalwarp/gdaladdo segfaults in 99% of cases on creating/modifying the tiled tiff files with jpeg, lzw or deflate compression.

#3 Updated by anonymous - over 17 years ago

  • Resolution set to fixed
  • Status changed from Open to Closed

This problem in gdal has been fixed (see http://bugzilla.remotesensing.org/show_bug.cgi?id=757), but is only available in cvs versions of gdal (the latest gdal, 1.3.2, doesn't include it).
