Problem Description:

BUGID: 1045302

	When attempting to read a bar file a segmentation
	fault (core dumped) error occurs.  Both with t and 
	x options.


	The original problem has more impact than it would appear.
	It looks like the Sun3/3x distributed bar *creates* tapes 
	that cannot be read using your patched bar or by other 
	system, e.g., 386i and Sun4/4c (I was using the SunOS 
	distributed version on these systems).

	This is what you see when bar tape created using the 
	distribution version of bar from a Sun3/3x system is read 
	on another system (Sun4/4c or 386i) or with the patched 
	Sun3/3x version:

	# /usr/tmp/bar tvf /dev/rst0
	bar: Insert volume 2 and press Return when ready.
	bar: Insert volume 3 and press Return when ready.
	bar: Insert volume 4 and press Return when ready.^C# 

INSTALL:

"sun3/bar" will work on both sun3 and sun3x architectures.
"sun4/bar" will work on both sun4 and sun4c architectures.
