Full Text Bug Listing

The game crashes right after you log in and the data is loaded, at the moment
when you should see the rendered surroundings.

Reproducible: Always

Steps to Reproduce:
1.Run Eternal Lands (el), preferably in terminal to see the error message
2.Log in

Actual Results:  
Game segfaults.

Expected Results:  
The game should have run normally (no segfaults).

Here's the output of 'emerge --info' command:

I'd just like to mention that compilation goes without a flaw. I even tried to
fetch the latest client from the cvs, compiled it, and it still segfaults. Now,
what makes it interesting is that the static (32-bit) precompiled binary, which
can be downloaded from their site, works without a flaw. I've also tried to
recompile all of the direct dependencies to no avail. I also tried to trace the
segfault by compiling the client with debug symbols, and it didn't help (the
segfault probably occurs in some of the underlying libraries, I got something
"blahblahblah in ??" when it occurred). I've also verified that this is
amd64-specific problem (my bro's x86 machine had no problems with it). One
thing that might be the problem is my usage of some of the testing packages (I
tried using the stable nvidia-drivers, though, and nothing changed). On the
other hand, I don't see any library which is used by EL to be a test-masked.

I'm not seeing this on my amd64.
Can you provide attach backtrace please?
http://www.gentoo.org/proj/en/qa/backtraces.xml

My backtrace won't provide any useful information - the system's binaries are
stripped of all debugging symbols (except that one time when I tried compiling
EL with debug symbols, but it doesn't help either). Now, I'm using
gcc-3.4.6-r2, so I'm thinking if that may be the problem? Seeing that other
people have no such problems, I'm beginning to think that it's only occurring
on my machine. Btw, EL 1.3.3 stopped working after I updated the world at some
point. I have no idea what to do (except to switch to new gcc 4.x, but it will
take a lot of time to recompile the system).

You need to follow th GCC upgrade guide.
http://www.gentoo.org/doc/en/gcc-upgrading.xml#upgrade-general

Re-open when you have done this and still have this error

I've upgraded my gcc, and the problem persists (hey, at least I got my gcc
upgraded, eh?). I'll try to rebuild some of the game's dependencies with
debugging information, and then run it through gdb.

Created an attachment (id=119118) [details]
Backtrace with (I hope) some useful information

I'm not sure if I got all of this right, I hope I did. Unfortunately, I didn't
recompile my glibc with debugging symbols. If it would be more useful to do
that, let me know.

OK that's showing an error in the OpenGL part shipped by nVidia.

Do other 3D applications work fine? For example, we have ut2004-demo in
portage, does that work? How about 3D OpenGL screensavers?

As far as I can tell, other games work just fine. I've tried playing X2: The
Threat - it works. Sauerbraten - works. Savage - works, bzflag (the only game
listed here which is not distributed in binary, I think) - works, several games
played through wine work as well. I've also tried using older nvidia drivers
(the non-masked ones), but as I said - it still segfaults. When did you last
update your packages?

Ah, sorry, I'd also like to add that non-game OpenGL applications work as well
(I use a screensaver which uses OpenGL), Beryl included.

Have you tried running EL without compiz and Beryl? Also try disabling
compostie, XGL and AIGLX if you have them enabled.

As to the packages, my system runs a full ~amd64 - which means all the latest
libraries.

Neither Compiz nor Beryl are running on my machine all the time (I mostly use
Beryl for showing-off due to the ugly bug in nvidia-drivers). Hm... I'm using
mostly stable branch (a package here and there is from ~amd64), the only direct
link to this problem might be nvidia-drivers (I use version 1.0.9755-r1, which
is marked as testing), but as I said earlier, I've tried using the stable
version to no avail. It might be interesting to have someone who runs mostly
stable amd64 to test this thing as well (apart from myself). I'm pretty sure
that some of the underlying libraries are messing things up, maybe the newer
libs you have work better? Btw, are you sure the segfault occurs in nvidia
drivers, since I'm not sure that my trackeback is good enough? I think I'll try
to get X up without some specific options in xorg.conf that allow the usage of
Beryl.

I have (finally) identified the problem. The problem was the '16bit-indices'
USE flag in media-libs/cal3d-0.11.0-r1. I've tried recompiling this library
without this flag, and the problem is gone. Then, just in case, I compiled it
again with this USE flag, problem is back. Tomorrow I'll do a check on x86
machine in order to see if it's arch-specific (so far I've encountered several
problems regarding the sizes of various integer types on amd64). Since you're
running testing branch, it would be nice if you could verify these findings
(just to make sure).

Good catch!

I've added this check to the ebuild, thanks.

re-opening as cal3d should not cause this crash, but it is a cal3d bug
