Package: torcs
Version: 1.3.0-1
Tags: patch
Severity: wishlist
If torcs attempts to start a race with the OpenAL audio backend
enabled, and OpenAL is unable to open an audio device, torcs
segfaults. The Plib audio backend just prints an error message when
it cannot open a device, and allows play to continue. When sound is
disabled, torcs doesn't even try to open a device. This is admittedly
a bug in OpenAL, but the attached patch to torcs provides a workaround
to allow torcs to work smoothly until the OpenAL issue is addressed.
Please consider this for application.
To verify the issue and solution, temporarily remove or displace
/etc/openalrc and (if it exists) $HOME/.openalrc; disable OSS (rmmod),
and start torcs.
