A xorg.conf with two devices containing the same input node will cause a double free and subsequent X server crash.

How reproducible:
Install the attached xorg.conf, adjusting the device path to a real wacom device. Start server.

MODIFIED

xorg-x11-drv-wacom-0.16.1-2.el6 is available in brew
Comment 7 Michael Boisvert 2013-01-17 16:11:47 EST
I was able to reproduce the crash in: xorg-x11-drv-wacom-0.16.1-1.el6. Upon installing xorg-x11-drv-wacom-0.16.1-3.el6 X started successfully with the supplied xorg.conf.

Verified.
