xf86ConfigLayout.inputs contains the information from the xorg.conf file. Passing this into xf86NewInputDevice means the device will get cleaned up on exit and the pointers in xf86ConfigLayout.inputs are left dangling. In the second server generation, this results in a server crash.
Also, rename pDev to pInfo. pDev is pretty much reserved for DeviceIntPtr types. Reproducible: AutoAddDevices off and xorg.conf input sections, trigger server regeneration.
