I've compiled iai_kinect2, and I've install essential dependencies(libfreenect2, image-pipeline, etc).But when I try to launch kinect_bridge, It still crashed. The same when I using rosrun. Then I run it directly using gdb, and here are what I got:

[mpatalberta]

Try the cpu only version does that work?

[kohrt]

Seems to be an issue with your Beignet installation. First of all try the CPU version as @mpatalberta suggested with the parameter reg_method:=cpu. Also you could try to use the Beignet version that the libfreenect README points at.
