Many compilers will produce a warning if an action is performed in a way which does not assure correct alignment. The popular targets for valgrind do not seem to care about aligned access, or perhaps unaligned access is just a bit slower. I have access to SPARC here so if someone can formulate a simple way to re-create the problem without GDAL installed then I should be able to help debug the issue.
