[Message part 1 (text/plain, inline)]

Installing emacs-snapshot results in error messages 
`Eager macro-expansion failure: (wrong-type-argument sequencep 769)'
while pre-compiling debian add-on packages like `apel' (see
attachment).  Since the errors occour with several packages I
assume a bug in emacs.

The problematic invocation is
emacs  -q -no-site-file -batch -l __myinit.el -f batch-byte-compile alist.el apel-ver.el atype.el broken.el calist.el emu.el file-detect.el filename.el install.el inv-19.el inv-23.el invisible.el mcharset.el mcs-20.el mcs-e20.el mule-caesar.el path-util.el pccl-20.el pccl.el pces-20.el pces-e20.el pces.el pcustom.el poe.el poem-e20_3.el poem-e20.el poem.el product.el pym.el richtext.el static.el tinycustom.el

with __myinit.el being:

#+BEGIN_SRC emacs-lisp 
(setq load-path (cons "." load-path))
(setq byte-compile-warnings nil)
#+END_SRC

It is possible to install emacs-snapshot as of
2013-07-24 but not as of 2013-08-04 or as of 2013-08-10.
Therefore I bisected the recent commit history.  First "bad"

Since I don't understand elisp I'm lost here.

Thanks for your attention, Gregor

This is apparently fixed in newer APEL.

This is just a warning and normally does not prevent normal execution
(it just falls back on the previous non-eager expansion).

> atype.el:28:1:Error: Wrong type argument: sequencep, 769

This is a real error on the other hand.

Sorry, I have no clue: Is this a bug to be fixed in emacs or are
these bugs to be fixed in those packages?


Ciao, Gregor

What do you mean by "packages"?
Do you mean some Debian packages other than apel; if so, which?
Or do you just mean "there are multiple files in the apel package which
all fail to compile"?
The latter problem is an apel bug, which has been fixed, as I said.

Yes, I saw multiple files failing and misunderstood that as
several packages.

I see, sorry I only checked the Emacs bug tracker for similar
problems.

Ciao; Gregor
