>Description:
	dump is segfaulting always for me after UFS2 update.
	segfault occurs on return from mapdirs() and the stack is trashed.

	e.g.
	% /sbin/dump -4u -f /tmp/foo /var
	DUMP: Found /dev/rwd0f on /var in /etc/fstab
	DUMP: Date of this level 4 dump: Sat Apr  5 17:55:38 2003
	DUMP: Date of last level 2 dump: Thu Apr  3 03:00:03 2003
	DUMP: Dumping /dev/rwd0f (/var) to /tmp/foo
	DUMP: Label: none
	DUMP: mapping (Pass I) [regular files]
	DUMP: mapping (Pass II) [directories]
	[1]   Segmentation fault      /sbin/dump -4u -f /tmp/foo /var

	Note, it won't fail if it compares with the epoch.
>How-To-Repeat:
