[Gdal-dev] gdaladdo throwing errors

[William Kyngesburye]

I have a very similar bug for this, which was fixed - the problem is  
actually in libtiff (your errors are slightly different):

http://bugzilla.remotesensing.org/show_bug.cgi?id=1204

You need to build libtiff from CVS to get this fix.

I see that you are on OSX (from your bug report) - have you tried my  
framework builds?  I ran my gdal_translate, tiffcp and gdaladdo on  
your huge test tiff with no errors.
