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.
