FreeGameDev

At first I would like to thank all of developers for their work on STK!
It is my son's favorite game. We used last version several times, it runs without
any problem on our Ubuntu 10.10 i386 machine.

But version 0.7 crashes (finishes its running immediately) randomly without any error message
(if I run it from terminal), or with simple message "segmentation fault". Sometimes we can use it 3-5 minutes, sometimes not.
I used 0.7 Static binary, i386 and the ppa what you offered, too, both have the same problem with my system.
I tried switching off compiz, windowed mode, problem persists. I do not know how to get
more useful information for the debugging :-(

I use Nvidia card with offered closed driver.

I can not do anything, in this situation we can not use version 0.7., but we would like it!
My son asked my to write you, maybe you can change something. :-)

Please write if you want more information.

Thanx,
nigra

The only thing I can suggest you (though I'm not a developer, may be they've got some other ideas) is to compile STK from source code with debug support. If this is done, one can launch stk via debugger and when game crashes it is possible to receive some useful information which can help to fix a bug.
However if I were you, I'd better wait developer's answer

Moving to appropriate STK forum.

Running stk in a debugger is done with :

gdb supertuxkart
run
# make STk crash...
bt

Now, I don't know what level of debugging symbols is included in the PPA, so if this provides insufficient information from the PPA binary you would need to build STK from source in debug mode

Maybe you met this bug: viewtopic.php?p=8709#p8709 but I'm not sure This bug has recently fixed ...

Well, that bug doesn't really fit the 'sometimes 3-5 minutes' - it should mainly causes a crash at startup (hmm - or perhaps the first time a certain place on the track is reached), and even this is unlikely to happen. So I don't think this is the case.

Are you using PulseAudio? That is always causing problems. Try either disabling pulse audio, updating it, and/or disabling sfx and music in the addon menu (and then restarting stk just to be safe).

Cheers,
Joerg

I installed STK from svn now, it works, we will test it soon.
Thank you for the idea!

Experiences:
- switching off sounds or "pulseaudio --kill" do not help, problem persists.
- shooting "toilet pump" is fatal several times: 70% of crashes happens meantime, but not every toilet pump shooting yields crash.
- I have two types of crashes: one frozes the screen (ssh from an other machine and "killall -9 supertuxkart" helps only), the other is just exiting from the program.
- "gdb supertuxkart run" and so on results only this type messages:
Program received signal SIGSEGV, Segmentation fault.
0x081b9df0 in ?? ()

... and it crashes in the case of shooting "toilet pump" me by the others, too.

- "gdb supertuxkart run" and so on results only this type messages:
Program received signal SIGSEGV, Segmentation fault.
0x081b9df0 in ?? ()

When you reach this stage, please enter "bt" then press enter; this will give us the information we need

Maybe it is my fault. Please tell me what does "compile STK from source code with debug support" mean.
I just installed it in the simple "./autogen.sh, ./configure, make, sudo make install" way.

If I'm not mistaken (I predominantly use pre-packaged versions myself too) you need to add some options to configure

{l Code}: {l Select All Code}

 % ./configure --enable-debug=yes

Did you think this : "./configure --enable-debug" ?

Edited: OK, meantime I got the answer :-), thanx!

I am trying this way.

Yes, that's exactly what you need

At this moment svn version does not work for me. I can choose the car, the track, but the race does not start.

Hi,

thanks. I know why this occurs - this is simply because we haven't tested make install recently, if you run STK locally without doing make install, this crash will not occur.

We will make sure to fix this

Using svn version program crashes only average 1 times/hour, so it is playable.
But bt does not give much informations...

Program received signal SIGABRT, Aborted.

nigra, is this a debug build? Your bt is very limited and not very helpful to us :/

nigra {l Wrote}:Using svn version program crashes only average 1 times/hour, so it is playable.

Well, that's still not acceptable

But bt does not give much informations...

That's strange if it is a debug build. Did you compile irrlicht in debug mode as well (though it should still show the stack trace). Did you enable the addon manager (if so, please disable it, which should be the default anyway).

Are there perhaps any threads active? Try using 'thread 1' and then 'where' (or bt), and/or 'thread 2', ...

Cheers,
Joerg
