Ciao Alessio!
I'll give your suggestions a try, thanks so much for your reply.
I forgot to mention that last week, Erik got me set-up with Wiki write privileges.
My interest is to get FUF/SURGE[1] running well under ABCL. It is a text generation component, which does some heave symbolic computation (unification of feature descriptions).
Besides the problem I mailed about, I am bumping into issues with ABCL (current) lack of tail recursion elimination. We discussed about it a little bit on #abcl, I'll send some e-mail on this topic once I get a better feeling for the code.
Thanks!
P.
