------- Additional Comments From thomas at suse.de  2005-09-06 06:37 -------
Now when len is OFF_T is it possible that sum->count (which is size_t) in
sum_sizes_sqroot() will rollover too at line:
        sum->count      = (len + (blength - 1)) / blength; ?

When we assume all variables have all bits set:
2^64 + (2^32 - 1) / 2^32 = 2^32 + 1

But sum->count can only represent 2^32 and thereofre sum->count will be 0.

Did I made a mistake here?
