  Log:
  SVN rev 180597 on 2008-07-18 15:05:14Z by kevlo
  
  Fix a longstanding bug, from Otto Moerbeck:
  if we're reducing a rule that has an empty
  right hand side and the yacc stackpointer is pointing at the very
  end of the allocated stack, we end up accessing the stack out of
  bounds by the implicit $$ = $1 action
