Bison VER 1.03 possible bug...

The last entry in ChangeLog reads as follows:
	Wed Aug 23 15:03:07 1989  Jay Fenlason  (hack at gnu)

I just received the latest version of BISON (1.03) and successfully
comiled it on an AT&T 3B2/310.  When trying it as a YACC substitute
on already working yacc grammer file, I received the following error:
	internal error, add_lookback_edge
	abort - core dumped

Being an internal error, I have no hint as to where to start looking
for the problem(s).  Any ideas?  I can send the grammer file if need
be.
