I've only tred with lzw compression. Symptoms: On windows within 10 or 15 seconds of running 'gdal_merge -o out.tif -co ""compress=lzw"" %indems%"" the standard MS dialog pops up saying so-n-so has crashed and would you like to send a bug report to MS-HQ. If you shorten the input list to 2 files, it works. (each input file is a 9mb CDED dem.) On linux the error is more like ""/usr/local/fwtools/bin_safe/gdal_merge.py: line 9: 3865 Segmentation fault $FWTOOLS_HOME/bin/`basename $TARGET` $@"" both windows and linux are using recent versions of fwtools. There is 1gb ram on the win machine and 768 on the linux one. }}}" defect closed normal GDAL_Raster unspecified normal fixed
