#89 torcs crashes with a segfault

[David Boucher]

I have this difficulty since torcs-1.3.0 (before all worked well).

I begin a new race, I can start. All is well displayed. But if my car touches another one or a wall or anything, Torcs exists with a segfault.

I'm on a AMD64 Gentoo machine. I removed the .torcs directory but nothing changed.

The console output is :

david@denebe ~ $ torcs

All those lines are written before me to begin the race except the last one...

My graphic card is an nVidia, the driver is the proprietary driver 1.0.9755 (I don't see any problem with it...)

Thanks.

I have installed torcs from sources, compiled it with --enable-debug. The last informations on the console are

The program is running. Exit anyway? (y or n) [answered Y; input not from termi---Type <return> to continue, or q <return> to quit---nal]

So the problem seems coming from OpenAl...

I then tried to switch the sound engine to plib and all works fine.

If OpenAL is broken on your platform this is the wrong place for reporting it. Thank you for the report anyway.
