[gdal-dev] OBus error when writing GeoTiffs

[Even Rouault]

Chris,

I'd bet too that you are hitting a problem with unaligned access on Sparc 
architecture when dereferencing some pointers that is present in the 
TIFFWriteDirectorySec function of the internal libtiff in GDAL 1.5.X

(I don't think that the compiler used would make any difference.)

This problem was reported and fixed as 
http://bugzilla.maptools.org/show_bug.cgi?id=1892

Current internal libtiff in GDAL 1.6.0beta has the above fix and should 
hopefully work.
