GlibC "fix" broke Evolution 1.4.6 on FC2

The problem is that Ximian refuses even to consider the problem. Why 
should I have to trace a bug in someone else's code? More to the point, 
how do I solve the problem? As matters now stand, Evolution is unusable. 
When it sends and receives mail, it has a fifty percent chance of crashing.

Here is the output of BugBuddy on my system:

Distribution: Fedora Core release 2 (Tettnang)
Package: Evolution
Priority: Normal
Version: GNOME2.6. unspecified
Gnome-Distributor: Red Hat, Inc
Synopsis: Crash on Send/Receive Mail
Bugzilla-Product: Evolution
Bugzilla-Component: Mailer
Bugzilla-Version: unspecified
BugBuddy-GnomeVersion: 2.0 (2.6.0)
Description:
Description of the crash:

Whenever I do a Send/Receive, especially if there's any mail in the box,
the program crashes.

Steps to reproduce the crash:
1. Start Evolution.
2. Click Send/Receive.
3. [It doesn't get that far]

Expected Results:

Download mail.

How often does this happen?

Has happened three times in thirty seconds. My e-mail client is
unusable.

And here is what Ximian said about it:

/------- Additional Comments From Gerardo Marin <mailto:gerardo at novell.com> 2004-11-11 18:00 -------/

*** This bug has been marked as a duplicate of 43160

And here are the relevant comments from some of Ximian's people, when this issue evidently came up *a year and a half ago*:


I can't find anything wrong with our code. I think there is just
random memory corruption happening somewhere, except I can't find it.
Also, mail_importer_init() is called fairly early in owner_set_cb() so
the memory corruption has to happen before then.

if all the crashes were in g_module_open(), I'd be blaming libc right
about now, but unfortunately there are even a few crashes in
mail_importer_module_init() which is a symbol loaded from each
importer module.

As far as I can tell, there is definetely no memory corruption
happening within mail_importer_init(). looking at some of the
backtraces, you can tell the correct (strdup'd) string is making it to
 g_module_open(), but the string passed to dlopen() by g_module_open
is *not* the same pointer, so I wonder if glib is doing something
fucked? Somehow I doubt this, but...*shrug*

for all I know, this memory corruption could be in the shell or
calendar or addressbook or summary...or... anywhere.

#14 0x40ec9ce4 in _g_module_open (
    file_name=0xfffffe00 <Address 0xfffffe00 out of bounds>,
bind_lazy=0)
    at gmodule-dl.c:93
#15 0x40eca090 in g_module_open (
    file_name=0x8218cc8
"/usr/lib/evolution/1.2/evolution-mail-importers/libmbox.so", flags=0)
at gmodule.c:231

gmodule.c from glib 1.2 (which is where all the reports are afaict)
doesn't do anything with the filename, it just passes the same pointer
that we pass to it. but from the bt, those 2 pointers differ. I have
no idea how. "Not Possible"




/------- Additional Comments From Jeff Stedfast <mailto:fejj at ximian.com> 2003-05-19 14:42 -------/

hmmm, as far as the second type of trace, where the crasher is in
mail_importer_module_init(), this bt seems the most complete:

http://bugzilla.ximian.com/show_bug.cgi?id=41495

if one looks at that bt, one has to wonder if the
corruption/bug/whatever is within gconf?




/------- Additional Comments From Jeff Stedfast <mailto:fejj at ximian.com> 2003-05-19 14:48 -------/

nah, on closer inspection it doesn't seem to be gconf. higher up in
the callchain, there's an invalid pointer being passed to
parse_default_uri() ?

I dunno, maybe the bt is corrupted too, who the hell knows.

this bug report is a complete waste of time to even bother looking at
imho :\




/------- Additional Comments From ettore at ximian.com <mailto:ettore at ximian.com> 2003-05-19 17:50 -------/

If the problem is memory corruption, then it can't be in shell or
summary since the problem used to happen with 1.2 when things were in
separate processes.  So it must either be a bonobo-activation/oaf bug,
or a race condition in the mailer code.




/------- Additional Comments From Not Zed <mailto:notzed at ximian.com> 2003-05-19 21:11 -------/

Given that the 1.3 ones seem quite different from the earlier version
ones (none of those are in mail importer init?), it is probably the
strongest indication that the problem isn't actually with evolution code.

i.e. my first impression and still strongest would be that it is a
problem in libdl.

Probably the next likeliest candidates are some problem in the
indexing code, and/or the mail importer code.

All areas, but particularly libdl, get heavily exercised at that
initial startup stage - mail_importer_init is run at the same time as
async tasks to open folders which are the first real calls to camel,
and a lot of symbol resolution is happening.

Without some sort of reliable reproduction scenario though ... and we
dont even have any of the output from the terminal either, if there is
any.

I think i may have seen this once, but i'm not sure.  I know i have a
known buggy dynamic linker w/ multithreaded apps.

FWIW some of the dups dont look particularly related, but only maybe
half a dozen.




/------- Additional Comments From Dan Winship <mailto:danw at novell.com> 2003-05-20 07:51 -------/

Yeah, I wasn't paying enough attention and didn't notice that a
bunch of them are crashes in other threads while mail_importer_init
merely happened to be running. Although many of those are crashes
in libdl still, so it may still all be related.
