Erm... It _can't_ be an inode number. Something is very fishy there.
	a) names are different, otherwise stat() would give the same
results both times it had been called. It didn't.
	b) actual inumbers are also different - see above for the reason
why.
	c) it might be an effect of getdents() returning crap (i.e.
giving bogus inumbers which ls(1) trusts). However, I don't see any
obvious ways to get corrupted directory tricking getdents() into that
output.

	Alex, could you do strace of that? It would clarify the situation.
