Can't upload attachment here; got 500 internal server error.

After some testing, it does not seem to happen when MESA_DEBUG=context and MESA_VERBOSE=all.

I get access denied trying to view this link. Can you try again to upload here? I had to try multiple times yesterday but it eventually worked, otherwise can you place it somewhere with public access?

I tried to run the game but it's missing a library on fedora which it seems needs to be built from source and configured to run as a service or something like that which I'm not willing to mess around with.

Anyway are you able to either build mesa from git or use a ppa (assuming you are using ubuntu) [1] to see if this is still happening in the current dev version of mesa/llvm?

I'll also try to upload it here again, although it will probably take a long time (am currently downloading my dump with 0.5 MB/s to upload it here...).

I'll update my local version of mesa to the latest git commit once I can (am not currently on that computer).

Another thing to note: Yesterday I tested for ~1 hour with mesa_glthread=true, and it didn't crash.
Although previously even with mesa_glthread=true, crashes could happen every 30 to 120 minutes, so I can not be completely sure yet, that it is mesa_glthread=true causing it, but I *think* it is. I suppose setting those debug variables just prevented some race condition by causing mesa to run slower.

Also if you still want to attempt to run the game: Try running the game with SDL_AUDIODRIVER=alsa and SDL_VIDEODRIVER=x11, that should fix your problem.
Yes, the devs don't make it easy for linux players to run their game.

PS:
I use Arch Linux.

Oh certainly don't upload that here :P I thought it was just the backtrace you were trying to upload.

Thanks.

I'm still getting: error while loading shared libraries: libsndio.so.6.1: cannot open shared object file: No such file or directory

At least they have released a 64bit version I guess, so they are trying. The 32bit version was useless.

So I've tested it for a few hours now, and it does not seem to be happening anymore.

NVM it just happened again, exact same error too.

Seems like it's not mesa_glthread causing it. It just happened again with mesa_glthread=false.

So yeah, it still happens with or without mesa_glthread as of commit 7728720f07a1f0931d7d394d5842de3803e9192b.

I need to do more testing to find out if setting either MESA_VERBOSE or MESA_DEBUG prevents it, as it seems like it's not happening as often as before (perhaps due to a game update?).

Just crashed with MESA_VERBOSE=all and MESA_DEBUG=context, but I got a nice error message:
Mesa: User error: GL_INVALID_OPERATION in glVertexAttribPointer(non-VBO array)
ns2_linux: ../src/mesa/state_tracker/st_atom_array.c:675: setup_non_interleaved_attribs: Assertion `attrib->Ptr' failed.

It's likely a game bug considering the error message but this could be confirmed if you grab an apitrace [1] of the crash and upload it to google drive (or somewhere like that) and link to it from here.

https://github.com/apitrace/apitrace/wiki/Steam

I haven't gotten an apitrace yet, although I am now 99% sure that it's a bug in the game, since another user had the issue with the proprietary nvidia drivers.

I'll close this now, since it obviously isn't something Mesa should attempt to fix.

Thread on the official forums by said user: https://forums.unknownworlds.com/discussion/154226/linux-random-segfaults

I also got the same segfault in libc.so when I was just using the mesa libs from the arch repository, probably because assertions weren't included in that version.

Thanks for your help though, it was much appreciated!
