Odd crashing..

[schene]

Hi all,

i've been experiencing strange crashes on Nexuiz as long as I can remember.
I'm running Gentoo Linux with Nexuiz 1.5. After 5-20 minutes of gameplay, the game crashes and i get error that Nexuiz recieved signal 11. Nothing else.
I saw on another topic that I should see gdb for debugging. There I found few lines that you might see useful:

Code: Select all

And then the crash:

Code: Select all

That was with GLX version. With SDL version i get major graphic corruption after a while (HUD disappears, fps drops to under 10, weapon model looks strange...).

I've tried multiple versions of nvida drivers (8776, 9631, 9746, 9755, 100.14.09), same thing with all versions, except 9755 gave me artifacts and crashed in every 3D application.
Here's some info about my system:

Bus Location:    01.00.0


I'm not sure if it's the problem in the system or the game. Earlier every 3d application gave me artifacts and crashed sooner or later. Then i upgraded to the newest drivers and disabled AGP 8x and AGP FastWrite support from my BIOS. I also had to turn AGP support from the nvidia driver completely off. This helped for everything except Nexuiz.
I remember having AGP related problems before too, with other video cards on Linux. I've got Abit NF7II motherboard.
I'm not worried about the performance hit of NvAGP 0 option. I just want to get stable computer where Nexuiz also works. Without the AGP hassle i've managed to run Nexuiz longer than with AGP enabled tho.

Thanks in advance. Sorry for any verbal errors in the post, I don't speak english as my native language. I hope you can still understand it and help me. If you need any extra information, just ask.

How did you get version 1.5, that's stone age. Even Debian has a newer version... get 2.3 from http://www.alientrap.org/nexuiz/.

Anyway, that backtrace is useless because you compiled the engine yourself without debug info. Compile it with debug info to get an useful backtrace (make cl-debug instead of make cl-nexuiz).

lol

Ahh, lol sorry.. That's what you get when you read topics from the iron age after being awake for 30 hours.. I got the 2.3 version. >_>

Anyways.. um, I cannot find the debug flag from Gentoo ebuild..

[ebuild R ] games-fps/nexuiz-2.3 USE="alsa maps opengl sdl -dedicated" 0 kB

Should i use the one from Nexuiz homepage instead?

Yes, that doesn't contain debug info directly - but we can use the addresses it produces (actually, the binaries are just stripped versions of the ones in http://141.2.16.3/nex/nexuizdebug20070531d_2.3.zip so we can use addr2line to get lines from crash dumps).
