(Actually, I should've said the increases in the byte and object
counts, when each .elc file is loaded.)

It wouldn't, but if it does happen (and I don't think it does,
either, but I don't recall for sure) it would be a reason for the
numbers not to be *exactly* the same, so then a very small
discrepancy wouldn't be a big problem. But like you say, I don't
think it happens.

Barring the obvious, like local hacks affecting the byte-code
optimizer, or some local bug causing character encoding conversions
to be applied to byte-code strings, I have no idea. But since I have
no other good idea how the 20K difference came up loading a .elc
file, I figure breaking the problem down might help. For example:
First, confirm that some file foo.elc to be loaded is (functionally)
the same, and that it consume different amounts of storage, on the
two systems. Then split it apart (binary search, one S-expression at
a time, whatever) and see if there's some particular kind of
expression in the .elc file that consumes different amounts of
storage on the two systems. If we know what it is, perhaps we can
figure out why it's handled differently. But if the files are
different, then the problem isn't differing storage consumed by
(identical) loaded objects, and we go off in a very different
direction....
If people want to expend that much effort on it, of course.
