Description Jia-Shiun Li 2014-07-17 12:38:54 UTC 
at end of execution, executable terminates with bus error when calling vaTerminate() like below:

jsli@jsli-bsd:~ % vainfo 
libva info: VA-API version 0.35.1
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/local/lib/va/i965_drv_video.so

It is a use-after-free bug already fixed upstream[1]. Supposed to be included in v1.3.2. Not sure when will v1.3.2 be released so here is the patch picked from upstream to fix it for now.

Tested with FreeBSD version 

FreeBSD jsli-bsd 11.0-CURRENT FreeBSD 11.0-CURRENT #19 r268599: Mon Jul 14 11:00:28 CST 2014     jsli@jsli-bsd64:/usr/obj/usr/src/sys/GENERIC  amd64

i915kms.ko loaded, and C2D E7400 / G45 chipset. Also tested ok on nVidia G105M with libva-vdpau-driver and nvidia.ko built from ports.
