Yes, that is definitely a bug in xfs. It's also a bug in arlad. Can you add
`printf ("name: %s %d\n", dp->d_name, dp->d_reclen)' in one of the cookie
loops too find what directory that is corrupted.

The try to find the file in arla's cache directory. The converted
directory's filename ends with '@' and will contain the information that
the kernel reads. Then try to parse the file, or send it to
({lha,map,assar}@stacken.kth.se) and we'll try to figure out why it
happens.

I've commited your patch. Thanks.

Love
