The crash of the torcs application when the car first crashes is
related to an issue with OpenAL MMX on AMD64.  Specifically, there is
an issue with the vector multiplication algorithm when compiled with
gcc 4.x and executed on AMD64.  As a workaround until OpenAL has been
updated to fix this issue, torcs can be run successfully by running
`export OPENAL_DISABLE_MMX=1` prior to starting torcs.  This is only
useful for AMD64: this problem does not occur on any other
architecture (i386 can actually process the generated MMX binary, and
it is not compiled for other architectures).
