[Linux] Random crash after joining marine team and waiting to spawn

ceribik

I crashed shortly after joining the marine team and was waiting to spawn (I might have been spectating another player). This was the first time it occured and isn't reproducible. Luckily, I had gdb running and attached as I've been trying to get a backtrace of another random crash that i get once every day or two.

System
Arch Linux 64-bit
GeForce GTX 560 Ti (nvidia driver 340.24)
KDE 4.13
Linux 3.15

Looks like the old good shotgun fire crash. It won't pop up often but it's a known issue. If someone (you, a spectated player, a team mate in the vicinity) fires the shotgun you may crash. However, if you haven't crashed the first time you won't at this game session. At least that's what I can tell from my experience.

Good to know. Thanks.

I think I might have fixed this for myself. I cleaned the shader cache (~/.config/Natural Selection 2/cache) about a week ago and I haven't had a crash ever since.

Like I said, it doesn't happen often. But it does from time to time. Clearing the shader cache may help if you updated the videodriver recently, the game recompiles all the shaders in that case. Maybe some older versions get in a way.
