If I recall correctly, I found two bugs on ARM/debian processors several years ago. One of which is the one referenced above which is due to a problem in the type definition in the adler32_checksum in File-RsyncP-0.68. I believe the other problem was in the Debian lenny library for md5sum which resulted in inconsistent checksum naming of pool files relative to x86 versions. ------------------------------------------------------------------------------ Slashdot TV.
