This crash was observed on one of our robots (clamps), probably on shutdown.

Ubuntu Trusty, ROS Indigo, amd64.

Segfault happened at: 0x7f519d708c80 <freenect_close_device+64>

I can't tell whether that actual problem is here or in libfreenect, and I can't figure out how to copy and paste the stack traceback from the Ubuntu crash report. I'll try to get a real gdb traceback if I can reproduce this again.

@jack-oquin Thanks! I've never seen this error before.

Happened again today. Different address, but same offset in freenect_close_device.

No core dump. I forgot to set ulimit. But, it's probably reproducible.
