>Description:
	I get the following gdb output:

[4:23:323]root@repeat:~> disklabel -R sd7 cdc.label 
Segmentation fault (core dumped)

>How-To-Repeat:
	This is the disklabel (I got it from the disk):

# /dev/rsd7c:
type: SCSI
disk: SCSI disk
label: fictitious
flags:
bytes/sector: 512
sectors/track: 52
tracks/cylinder: 15
sectors/cylinder: 780
cylinders: 1632
total sectors: 1295850
rpm: 3600
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0		# milliseconds
track-to-track seek: 0	# milliseconds
drivedata: 0 

8 partitions:
#        size   offset    fstype   [fsize bsize   cpg]
  a:  1295850         0    4.2BSD        0     0       	# (Cyl.    0 - 688296*)
  c:  1295850         0
  g:  1295850         0    4.2BSD

>Fix:
	I have not looked at it yet.  I'm still trying to see if
changing the label itself will fix the problem.
