Hmm. I could be wrong, but I don't remember any changes in the 23.X
byte compiler / interpreter stuff making old (22.X, not 19.X ;-)
byte-code incompatible.
Any such fails is more likely to be from the lisp code than the byte-code.

(Of course 23.X files use a different coding system, so they are not
back-compatible.)

"Should" does not imply "must", of course. You can use compile-time
tricks to do almost anything, including generating code which bears no
relation to the original lisp...
