Hello Andy,
Hi developpers,

Thank you so much for having given a look to this problem. After digging into the
debian packages and trying to rebuild from latest 2.7.99-4 debian source, I
understand that your suggestion was actually already included by Andreas:

	- I know it sounds surprising, but having built myself in the past, and
	  being quite prudent in installing official debian package [list-store
	  missing symbols ...] I now have to make sure that what is installed
	  and running on my machine is the latest 2.7.99-4! I'll do that today

But I have had another type of bug, which I beleive is not related to the one
you looked at, which rarely appears and occurred today, so here it is:

	*** glibc detected *** guile: corrupted double-linked list: 0x08a1ca60 ***
	======= Backtrace: =========

Attached are 2 files: the output that was printed in the terminal and the gdb
backtrace.

	[I know I have to port my code, it's far from being easy: it depends on
	gtrees [recently received support from the creator to make it running in
	guile-1.8 and guile-pg, a prehistoric version which will remain so until
	it's maintainer goes forward [i think he made it clear that he will],  ... 
	gtrees and guile-pg force me to stay in guile-1.6]

	[All these apps are between 13.000 and 30.000 lines of pure scheme code:
	quite a lot of work, to port and test! but I started already...]

In the meantime, I still hope that you and guile-1.6 maintainers can offer a little
support and help me debug:

	 I'll do all my best to provide as much as possible info to get rid of these
	 2 nauty bugs.

Many thanks again,
Long live to guile! I am looking forward to port and test my code with guile-vm!
Cheers,
David

Hi David,

I'm happy to help, and glad to hear things are going OK. You probably
have the largest guile-gnome-using apps out there... Also, one of these
three lists is probably enough ;)

I couldn't tell from your backtraces what went on. Be sure to install
the debug packages so that gdb can give symbols.

I just downloaded
http://vychodil.inf.upol.cz/research/development/gtrees/download/gtrees-0.5-alpha.tar.bz2,
and it seems to compile fine against 2.0. I did a (load-extension
"./libgtrees" "define_gtrees_module") and that worked, and then
(use-modules (gtrees-module)) and that worked too.

Perhaps you will be able to skip 1.8 ;-) But it should work with 1.8 as well.

No such luck with guile-pg, it will need patches. I even tried applying
debian's patches to see if that would help, but guile-pg uses gh.h.
Copying Thien-Thi, who appears to be the upstream: what is the right
thing to do here? Get it into a project on savannah in git hosting, no?

Sorry, i don't understand.  What does "it" refer to?

The right thing to do in any case is to identify the platform
specific parts, write tests to detect them, and code to accomodate
for them.

I started this with src/gi.h, but that is just the beginning.

   Referring to guile-pg.

I'm not completely comfortable w/ that.  Besides
being a control freak, i'm also loosely connected.

Can we have a git repo somewhere, then?

Yes. Just made things working both with guile-1.6 and guile-1.8 [on the same
machine I mean], by changing the module definition as this [if others would like to
do so...]:

;; --
(define-module (struct gtrees))

(let ((ef-ver (string->symbol (effective-version))))

Well, as much as possible, due to the amount of work I have, I'll stick to debian
packages until I finish the application I am working on, then I'll try 2.0 and
guile-vm, I can't wait! but I have to :-(

If you remember, thanks to dsmith, on xchat, I could produce a guile-pg [debian]
package patched that works with guile-1.8 [the problem was a dependency one: here is
what I wrote to myself:

;;;
;;; Debian package [patching guile-pg-0.16]
;;;

A] Getting the source

	cd ~/alto/admin/guile-pg
	apt-get build-dep guile-pg
	apt-get source guile-pg
	cd guile-pg-0.16

B] Changing the dependency towards guile-1.8
   
 	cd guile-pg-0.16/debian
	
   perform the following change

<	Build-Depends: debhelper (>> 4.0), quilt, libpq-dev, guile-1.6-dev
>	Build-Depends: debhelper (>> 4.0), quilt, libpq-dev, guile-1.8-dev

	But I also wrote something about patching libpostgres.c and .h,
	[postgres-7.4: the only SW that's still is not a debian package [in my
	dependency 'little tower'] but a manual compilation [and they are @ 8.4 now,
	so quite late on this side too ...] can't find right now but if people are
	interested i'll make that info avalable too, let me know.

C] Then I changed the module definition [attached]

;; --

So I was wondering, in order to be as practicle as possible and save 'lost'
debugging time, is it possible to install both guile-gnom0 and guile-gnome2 on the
same machine ?

	I think I tried and didn't work, but I might be wrong.

That would fantastic because I could right away porting the development I am doing
and later on port the old apps.

Yes. Just made things working both with guile-1.6 and guile-1.8 [on the same
machine I mean], by changing the module definition as this [if others would like to
do so...]:

For what it's worth,

   (load-extension "/usr/local/lib/gtrees-0.3/libgtrees" "init_gtrees_module")

is more concise.

Cool!

Should be possible, yes. You should not load both of them into the same
Guile program, but I don't think they overlap at the file level.

Let me know if you find any problems.

Done!

Is this any better? [I have no more 'no debugging symbols found' messages

Unfortunately I don't see the problem. All of the bt is in GTK+ code.
But surely it was a case that we freed something that was supposed to be
freed in some other way (the g_slice thing again).

Try valgrind perhaps?

Hi Andy,

The backtrace error of the message you answered is the 'corrupted double-linked ...' 
which occurs 'rarely' and always gives a long output in the terminal + a backtrace ...

;; -- the 2 errors might be [or are for sure] related, but...:

The 'gslice error' occurs 'all the time'. This tells me that they are not 'the same'
and I still wish to try to debug. I have an idea:

	1]	here below is a 'full' backtrace [after installed guile-1.6-dev nostrip...]
		- may be it's better then the previous one? [for this error GSlice I mean]

	2]	if not, as I have a full source tree ready to compile as many times as I wish,
		using libglib 2.22.4-1 and 2.18.9-2:

		-]	I could temporarily change the source code, with your help, to open
			a log and write in it these info you need

		what do you think?

> Try valgrind perhaps?

I tried, but so far without much success: without help I am not sure I will achieve any 
useful result, and I have a feeling it would be quicker to temporarily change the source 
code, would it not be?

Thanks,
David
