segfault when restarting a race many times

Hi,

I'm training a robot with computational intelligence techniques. For now I'm
using NEAT. After about 1000 race restarts torcs crash. Before this, about
700 race restarts, I percept that the tyres didn't render right, only the
sides were rendered and the middle didn't appear, you can see the track
throw the tyres. You can also see the suspension in the middle of it. I was
using the f1 car that comes with torcs.

I'm using Ubuntu 9.10 and Torcs 1.3.1 using the plib sound backend. If I use
OpenAL the game crash very early, after some restarts. If it's interesting,
I can also provide a bt. I'm also using the patch used in the CIG
championship:
http://sourceforge.net/projects/cig/files/Championship%202009%20Linux/1.3/champ2009patch-1.3.tgz/download

Here is the bt for the problem I described first:
