No, but it's pretty high on my list.

In general, there’s no particular problem with it, but you’re interfering
with the guts of byte-compilation in cc-defs.el, we don’t (and can’t really)
guarantee that functions with side effects like #'set-buffer won’t cause
problems if those side effects aren’t wrapped, when you do something like
that.
I came on the fix by applying the following patch to bytecomp.el, setting a
GDB breakpoint on Fdenominator, once that tripped setting a breakpoint on
set_buffer_internal, and then looking at the Lisp and C context for
unexpected values of the buffer.

[issue]: file.el compiles to null file.elc
13 years, 2 months
Alan Mackenzie

Hi, XEmacs.
Download CC Mode 5.32 from
<http://sourceforge.net/projects/cc-mode/files/cc-mode/cc-mode-5.32.tar.gz...>.
Unpack the archive and byte compile it as instructed in the README,
i.e.:
xemacs -batch -no-site-file -q -f batch-byte-compile cc-*.el
, where xemacs is, e.g., 21.4.22.
Note that the resulting cc-align.elc is only 576 bytes big and, on
closer examination, is content free. This is a bug.
Note: in an actual XEmacs session, M-x byte-compile-file compiles
cc-align.el properly.

I can compile that test case without problems. Do you both have the latest
versions of bytecomp.elc, cl-macs.elc and, just to be sure,
byte-optimize.elc?

File.el compiles to null file.elc
13 years, 2 months
Alan Mackenzie
Alan Mackenzie
Hi, XEmacs.
XEmacs 21.5.b31, 21.4.22
At the moment, when I compile cc-align.el on either of the two versions,
the resulting cc-align.elc is empty. More precisely, it looks like
this in its entirety:
;ELC^T^＠^＠^＠
;;; compiled by acm(a)acm.acm on Fri Sep 9 10:53:29 2011
;;; from file /home/acm/cc-mackenzie-2011-08-30/cc-align.el
;;; emacs version 21.4 (patch 22) "Instant Classic" XEmacs Lucid.
;;; bytecomp version 2.27 XEmacs; 2000-09-12.
;;; optimization is on.
;;; this file uses opcodes which do not exist in Emacs 19.
(if (and (boundp 'emacs-version)
(or (and (boundp 'epoch::version) epoch::version)
(string-lessp emacs-version "20")))
(error "`cc-align.el' was compiled for Emacs 20"))
(or (boundp 'current-load-list) (setq current-load-list nil))
cc-align.el hasn't changed since it last compiled, but some of the files
it requires have.
Is this a known bug? What can I do about it?
