To minimize the time spent scanning all of the directories in pass 2 (Check Pathnames), fsck uses a search order based on the location of their first block. Zero length directories have no first block, so the array being used to hold the block numbers of directory inodes was of zero length. Thus a lookup was done past the end of the array getting at best a random value and at worst a segment fault. For zero length directories, this change allocates a one element block array and initializes it to zero. The effect is that all zero length directories are handled first in pass 2.
