Description (last modified by )
When adding overviews to an LZW compressed TIFF, and using the average resampling, I get bus errors at higher overview levels. Happens with both color and grey images. No crashes with default nearest resampling. GDAL 1.3.2, libtiff 3.8.2 and latest CVS. This is what I get in the Mac OS X crash log trace: Command: gdaladdo Path: /usr/local/gislibs/bin/gdaladdo Parent: bash [12048] Version: ??? (???)

New info. I tried libtiff from a recent CVS - Nov 8. No crashing now, but a lot of errors. I get about a dozen of the same error block in libtiff: ERROR 1: colorlzw.tif:LZWDecode: Wrong length of decoded string: data probably corrupted at scanline 0 ERROR 1: TIFFReadEncodedTile() failed. ERROR 1: IReadBlock failed at X offset 0, Y offset 1 ERROR 1: GetBlockRef failed at X block offset 0, Y block offset 1 The overviews seem to be present - tiffinfo shows them all. But that's just the tiff directory, in QGIS all but the last overview are OK, the last one is corrupt. So, changes in the libtiff CVS between June and now have improved it, and hopefully help in figuring out what the problem is.

I believe this has been fixed in GDAL trunk using internal libtiff as described in #1758. Please reopen if you find otherwise.
