Any such fails is more likely to be from > the lisp code than the byte-code. I don't say anything about where the incompatibility comes from. If forced to guess, though, I too would suppose that it's from (or mostly from) changes outside the byte-compiler. What I do know is that I have code that works if byte-compiled in Emacs 22 or 23, but does not work if the 22-byte-compiled code is used in 23. And I believe that I have code that does not work if the 23-byte-compiled code is used in 22. My guess is that changes in the treatment of characters are mostly responsible for the incompatibilities I see, and those are probably mostly (entirely?) outside of the byte-compiler code.
