xfsprogs/repair/agheader.c - 1.4
        - Fixes a problem from the last bugfix checkin, picked up by QA on
          fuzzy, but not observed on troppo in my debug builds.
          Since sb_dirblklog is only 8bits long, we can no longer use a
          pointer to an integer when looking for non-zero memory - this
          gives alignment issues and takes us past the end of our dynamic-
          ally allocated SB memory.  Chalk one up to QA and electric fence.
