Yes, that fixes the problem, so generation works again.

hi berthold (and dan),

my apologies, i had introduced a bug in lexial instantiation.  the bug
was triggered by predicates that are used both in lexical entries and
grammar rules (i.e. only a sub-set of non-string predicates), thus was
not exposed in the limited amount of testing i had done yesterday.

dan, could you confirm this works for you, and then i re-build binaries
for berthold tomorrow?

                                                       cheers  -  oe

nb: ann, this is exactly about the code we discussed yesterday.  i have
now resorted to the latest variant i had proposed in that discussion:

  (defun lexical-rel-p (pred)
    (or (gethash pred *relation-index*)
        (and (stringp pred) (> (length pred) 0) 
             (char= (char pred 0) #\_))))
