guile-gnome-0 - guile-1.6.8-6.3 - random crash

guile-gnome-0 - guile-1.6.8-6.3 - random crash

[David Pirotte]

Hello,

	debian 		2.6.22-2-686
	ii  libc6           	2.9-12                      GNU C Library: Shared libraries
	ii  libc6-dev    	2.9-12                      GNU C Library: Development Libraries and Header Files

I know, guile-gnome-0 is obsolate ... But I have no choice right know and really really hope that
I can help developers to find out what the problem is and debug it ... 

It does not seem to be related to 'my programming and/or code'. Further more, I long thought it
was a libglib bug, but recently succeeded upgrading from a very old version to up-to-date one and 
the bug still appears:

	ii  libglib2.0-0            	2.22.4-1              
	ii  libglib2.0-0-dbg       	2.22.4-1              
	ii  libglib2.0-data        	2.22.4-1              
	ii  libglib2.0-dev         	2.22.4-1              

	ii  libgtk2.0-0                  	2.18.6-1              
	ii  libgtk2.0-0-dbg        	2.18.6-1              
	ii  libgtk2.0-bin              	2.18.6-1              
	ii  libgtk2.0-common      	2.18.6-1              

	ii  guile-1.6                            1.6.8-6.3        
	ii  guile-1.6-dev                        1.6.8-10

	ii  guile-gnome0-vfs                     2.7.99-4

	ii  guile-www                            1.1.1-3             
	ii  libguile-ltdl-1                      1.6.8-6.3             

I was able to produce a 'reasonable' backtrace: the only problem is libgwrap,:

	ii  libgwrap-runtime0     	1.9.6-3.2		
	ii  libgwrap-runtime2	1.9.13-1         	

	BUT

	there is only one libgwrap-runtime-dev file available and installing it would break guile-gnome-0
	because requires guile-1.8-dev [which conflicts with guile-1.6-dev, don't know why] ... 

The bug appears every few minutes of using the application, doing things such as selecting row in
a liststore, opening/closing user dialogs ... Its is unpredictable and can not be reproduced by a series
of precise actions, it is just 'random'

Here is what I could come up with, knowing that it's without  libgwrap-runtime-dev [which
could only be libgwrap-runtime0-dev in my case]:

Many thanks to give it a look and a try ... If there is anything I can do ... let me know of course

Cheers,
David

As long as you know this :) This was released *five years ago* :)

Are you using custom tree models? I bet it's something whereby we are
freeing something with g_free but it was allocated with g_slice_alloc.

What about this fix (from git revision
c7101904f2704b3cf7fbde5c02602be01ff37f2b, 2007-12-09), to
gtk/gw/gtk-support.c:

 }

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.

Shot in the dark:  I typically see these  if there is a double-free, or if
there
are writes to freed memory.

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?
