Hi everybody, 

I'm trying to use ar_track_alvar with uvc_camera. 
I launch the corresponding node on my robot, and as soon as it detects a tag, it died. And I don't have any log, just a stacktrace saying "[ar_track_alvar-1] process has died [pid..., exit code -6, ...]" 
Do you have an idea on the origin of the problem ? 
Thanks a lot
