Re: emacs-19.34 segfauls when built with Xfree 4.3.0 (glibc 2.3.x,gcc 3.2)

[Hin-Tak Leung]

That's a somewhat time-wasting question - if I am on linux with
gcc 3.2 glibc 2.3.x and Xfree 4.3.0 most certainly the linux
distribution I use come with a more recent version of emacs or xemacs.
(actually both). And my original post mentioned that I built emacs-19
successfully on a Xfree 4.1/glibc 2.0/2.1 system as well,
and that binary still works on the current system.

I want to use a elisp script called cemacs (for Chinese inputs)
but unfortunately the inclusion the MULE (Multi-lingual Extension)
since version 20 has broken it. It does continue to work with
xemacs-21.x, but that's besides the point.

Now back to my question: why emacs 19.34 segfault when built against
glibc-2.3 and Xfree 4.3.0? And please stick to the question... -
and please do not ask why I don't switch to xemacs, or use MULE.

Just to anticipate these two questions: MULE is no where as good
as cemacs (unfortunately, and please don't start an argument on why I
should use MULE even though it is inferior), and xemacs is too
bloated for my taste. So I would really rather try to keep using
a small installation of 19.34 (in addition to emacs 21 which came
with the distro), or port cemacs forward to emacs 21 (quite major
work, probably). The 2nd option is probably better for long
term, but until it is done, I will continue to try to build emacs
19 on current systems... and I would really like to find out
why it won't build.

have you tried using a more recent version of emacs? emacs-21.3.1 is
what i use and it compiled with gcc-3.2.3 on XFree86-4.3 no problems
(glibc-3.2.3) using using Lesstif-0.93.41. unless there is some reason
you WANT to use an older version?

in this case probably no one can answer your question w/o your investing
effort into debugging the matter locally.  as well, probably few people
are interested in helping you if you scold them.

of course, there is the option of hiring someone to work on this problem

Re: emacs-19.34 segfaults when built with Xfree 4.3.0 (glibc2.3.x,gcc 3.2)

[Hin-Tak Leung]

This is going more and more off-topic. My initial post was fairly
specific, and the one reply I got (asking why I don't use a more
current version) was already somewhat off-topic, because I did
describe my system in much detail and it would have been obvious even
at that point I had a (not yet disclosed) reason not to use a
more current version.

But unless of course, you would rather me switching to xemacs-21 instead...

(cemacs still continue to work under it, as the emacs/xemacs split
occurred before version 19, and the xemacs folks are less agressive
in making incompatible changes - which unfortunately is also the
reason of xemacs's bloatedness; however I believe MULE is going into
xemacs-24 or thereabout's so the issue will need to be addressed one day,
even if I switch to xemacs).

FWIW, I did search through the archive for "Fatal Error(11)".
And it seems to be the message for a general memory access error,
similar to the gcc's SIG 11 (probably identical to...), or
the rather uninformative "segmentation fault" whenever any program dies;
and fatal error 11 can occur under a lot of totally unrelated conditions,
but mostly to do with how undump works, memory aligment, etc.

So my guess is that it is probably going to be very sensitive
to how my glibc, Xfree86, or my gcc were configured and built and
any patches were applied to them; and there *might* be a chance
that a future system upgrade *might* magically fixes it.

In any case, the reality is that I only need emacs-19 to work in
the "-nw" enviroment for cemacs, and figuring out why it
segfaults under Xfree86 is a somewhat academic issue... but
I would still like an answer, an explanation, or (gasp) a
possible fix.

OTOH, if I really want a "currently supported" emacs for my purpose,
I could switch to xemacs-21 immediately and that would give me
a couple of years to look for other alternatives...

[Hin-Tak Leung]

(Sigh) This is getting more and more off-topic. You know, earlier posts
to similar questions (why does it segfault, "fatal error 11")
in the archive had instead concentrated
on the issue at hand e.g. in the archive around Jun 2002
there was an explicit patch (which I already use to get the
compilation going), and other people over the past 10 years' archive
had suggested running gdb on core dumps, doing a strace, etc on the
"Fatal Error 11" problem. So far neither you nor
"supposedly helpful" samuel had even suggested either gdb or strace.
or trying to get a core dump.

If you want my adaptability, I guess I would like to offer
a gdb back trace or something like that eventually, when
I get round to do it. Can you help debugging a gdb back trace?

(I would really like a straight forward "yes" or "no", rather
than going into further philosophical discussions).

(Sigh). I would have been a lot happier if one of you had
replied with "get me a gdb back strace" than having to digress
to lengthy philosphical discussion on reasons to use an
older version, or resorting to foul languages.

As I said, I would prefer a "yes" or "no" to the gdb debug
question. It isn't to difficult to answer either:
(1) "possibly, depending on how deep the problem is; can't promise"
(2) "Sorry no, no eperience with gdb whatsoever"

But you are trying to draw into philosophical discussion again.
(I guess that's still better than the "get a f*cking life"
or "cheeky f*cker" replies)

I suppose the inclusion of MULE and breaking backward
compatibility is the root cause - and my not wanting to use it.
But this is somewhat irrelevant. Other people may have other
reasons for wanting to run an old copy of emacs on current
systems, and a solution may be useful to others. The
preference to use cemacs versus MULE may be a very
small minority, but I don't think the same can be said about
emacs 19 versus emacs 21 in general. In a way, MULE has
exactly the same strength and weakness as the general emacs
"Swiss Army Knife" philosophy: it is useful for linguists
who want to do a lot of languages within a single document,
but it doesn't work particularly well for any one given
language. And a 30MB MULE installation versus 50kB cemacs -
a trimmed emacs 19 installation in parallel/addition to
emacs 21 is only 10MB.

If I had sounded impatient, I had not resort to verbal
violence as some others did.

Here is the long awaited gdb back trace and strace. It seems to die
at the same place that emacs-21/AIX dies if it is run over a slow
dial-up connection (there were two different patches for that, one of
them by Mr Stallman himself no less, if I remember correctly)
- probably not related. Thought I'd mention this just in case.

Interesting.  It dies deep inside the toolkit.

What happens if you compile Emacs without a toolkit?  (I'm trying to
find out if the toolkit is the problem.)

That's another pointless reply... you still have not offered
any substantial help - e.g. suggestion for compiler switches,
small modification at the source level, etc.

FWIW, I had tried both "-D_BSD_SOURCE" (the default)
and also "-D_GNU_SOURCE -D_BSD_SOURCE" (how the redhat
4.x rpm was built). Both binaries work happily with "-nw" inside
an xterm and seg-fault under X.

Thanks for another "I am trying to help and I am not saying anything" post...

(Sigh) A 3rd "See I am so helpful" post. Look - there is no
useful content in any of your three replies.

Other than my stated reason (an important old elisp script that
doesn't run under current versions), I think the memory foot-print
and launch-time could well be the reason for anybody wanting
to run emacs-19 or even earlier on current systems instead of the
current. As you say, it is a frequent-enough request, and I asked
a legitimate question that you fail to address anywhere close
in 3 posts...

Why can't you just try to answer a straight-forward question,
as you seem to suggest you "want to help"? As it turned out,
if I had mentioned cemacs (and mentioned that I don't want
to use MULE), I would be drawing myself into a
flame war regarding MULE's merits. That had seemed to be a
sensitive subject to some others (ttn@glug.org - who I believe
is possibly involved in MULE's development as I seems to have
come across that name in other projects). It is a fairly personal
choice - cemacs versus MULE, emacs 19 versus 21, and I don't really
need to explain why I prefer one to the other.

I asked a technical question and reported a possible bug
of an old unmaintained version of emacs, which I believe
some other people may like to continue to use for their own
reasons - those reasons are somewhat irrelevant to the question.
I would really prefer it to stay that way.

Bugs (and a crash is a sign of a bug) should be reported to
gnu.emacs.bug, not to gnu.emacs.help.

I find it hard to believe you will find someone who will debug this
for you in such an old version of Emacs.

I looked thru etc/PROBLEMS and found there an entry about crashes at
startup when Emacs is built with XFree R6.4; there's a patch there for
Xlib, which perhaps will help you (assuming that PROBLEMS describes
the same problem there).

Re: Re: emacs-19.34 segfauls when built with Xfree 4.3.0 (glibc 2.3.x,gcc 3.2)

[Richard Stallman]

    That's a somewhat time-wasting question - if I am on linux with
    gcc 3.2 glibc 2.3.x and Xfree 4.3.0 most certainly the linux
    distribution I use come with a more recent version of emacs or xemacs.

If it contains those things, it appears to be a GNU/Linux
distribution, not a distribution of Linux alone.  See
http://www.gnu.org/gnu/gnu-linux-faq.html.

    Now back to my question: why emacs 19.34 segfault when built against
    glibc-2.3 and Xfree 4.3.0?

We're not maintaining Emacs 19.34 any more, because it is obsolete.
Other people are free to work on it if they want to.

In contrast,, we might be interested in trying to fix this problem

    I want to use a elisp script called cemacs (for Chinese inputs)
    but unfortunately the inclusion the MULE (Multi-lingual Extension)
    since version 20 has broken it.

if you send a bug report with a precise complete test case.

We are certainly interested in improving MULE.  Could you write to
emacs-devel@gnu.org and tell us why specifically MULE is not as good
as cemacs for your usage?

[Hin-Tak Leung]

Yes, it is a GNU/Linux system.

As it turns out, the solution (adding '-z nocombreloc' to LDFLAGS)
fixes problem with building current version of emacs as well.

It is a problem with 'combreloc' becoming the default since March 2002 in
GNU ld so it affects very new GNU/Linux system when trying to build
all versions of emacs and xemacs, in addition to very new GNU/Hurd systems,
and any other system for which GNU ld is the default linker and for which the
version of GNU ld is less than 14 months old.

I'll address cemacs/MULE separately.

have you tried using a more recent version of emacs? emacs-21.3.1 is
what i use and it compiled with gcc-3.2.3 on XFree86-4.3 no problems
(glibc-3.2.3) using using Lesstif-0.93.41. unless there is some reason
you WANT to use an older version?

cheers,
Sam

emacs-19.34 segfauls when built with Xfree 4.3.0 (glibc 2.3.x, gcc 3.2)

[Hin-Tak Leung]

I am trying to build emacs-19.34 against glibc-2.3 and Xfree 4.3.0
on linux with gcc 3.2. The binary works with -nw switch, but
when I run it without -nw, it segfaults with Fatal Error(11).
So it seems to be an X-related problem.

I had an older binary which was compiled by gcc 2.95.x against
Xfree 4.1(?) and glibc-2.1 (maybe 2.0?) which still works on
this current system.
