not yet - because I wanted to see if all drivers crash first.

Not necessarily. We've hit lots of bugs nobody else hit, in Mesa, nvidia drivers, everywhere.

Did you try lower shader settings?
And not necessarily it's a bug in the driver, it could also be bad API usage that doesn't crash in other (more robust) drivers but that does de-stabilize fglrx.

lowered settings to:
Geometry: High Detail
Textures: 2048
FactionTex. on
Shaders: Average Shader

and again sigbus on flying to the relay. What could be considered 'safe' setting?

Safest would probably be 512 textures and no shader.

Detail level doesn't have to go very low, I think, but it could have an effect.

no shader, textures at 512.

Boy that was ugly (the relay). And still crash.

like something from a nightmare. On a second thought - I like it.

All those thingys disappeared when getting close and the crash happened when I turned away.

Turning away is a re-occuring theme.

Which driver versions did you try? Did you try a non-pre-release one? Cuz I remember people saying the beta2 worked on fglrx.

I used two who are in the testing stage for upcoming releases, I already reported the problems to the ml. Lets see if there is a reaction when everybody is back at their jobs ;)

In the mean time, if you want to release the next beta - don't feel the need to wait for me. But I would like to know WHICH fglrx version the reports used.

I would like to know it too ;)

People rarely post those details. I wouldn't mind it to be re-tested though.

That's a problem. Do you feel like debugging this? It could be veeeery time consuming.

depends, how long are you willing to wait? I am away from home for work 12h a day.. so.. everything I do takes some time.
The worse problem - I have no idea how to start.

energyman76b is it possible to trigger the segfault deterministically? If true, please provide a howto and maybe savegame. I can test on Ubuntu 11.4, Mesa r600g.

Or maybe event try to capture a opengl trace: https://github.com/apitrace/apitrace

An API trace would be most helpful, we've already fixed a few API misuses with them.

@log: I don't think Mesa will crash, it uses the DRI2 interface and I've tested it thoroughly with intel. The DRI2 is low-level enough that OpenGL API stuff doesn't matter much, and if it works with intel it's most likely to work with every other DRI2 implementation. Do test, but also try AMD's drivers.

the quickest way so far: fly to relay, fly around a bit, then set AR-17 and start autopilot. Crashs very reliablely. Or at AR-17 spend some time shooting asteroids, select Plainfield, engage autopilot and just fly. But there is no 'this crashs game in 3 minutes top' way to do it.

I always start with the campaign. so no savegame and I always flee Oswald in terror ;)

tried apitrace:
apitrace trace --output=vega.trace ./vegastrike
.
.
.
cannot execute suborders as Linear Velocity Matchership destroyed-no flightgroup
apitrace: warning: caught signal 11
apitrace: flushing trace due to an exception
apitrace: info: taking default action for signal 11

and no trace file?

wait - it landed in data! ahhh

so I got 2 tracfiles. 4.2G and 1.1G ....

They're text right?

So you could either compress them or take the few thousand lines (tail -n 10000 tracefile) and compress them, the useful bits should be near the end, but given that the crash is quasi-random there's no guarantee - it would be great to have the full trace, but at 4G I don't think it's possible ;)

the 1.1g file packed with p7zip is down to 170mb I could upload it at rapidshare.

Test: "fly to relay, fly around a bit, then set AR-17 and start autopilot. Crashs very reliablely. Or at AR-17 spend some time shooting asteroids, select Plainfield, engage autopilot and just fly" repeated 3-4 times for about 20-30 minutes

Tested on Ubuntu 11.10 with Mesa r600g and then repeated with Catalyst 11.11. No crashes.
