Runtime error when running dvo_slam benchmark

[bexilin]

Hello, @christiankerl, I finished compilation of dvo_slam without error on Ubuntu 16.04 with ROS Kinetic, and tried to run it on TUM dataset with command: roslaunch benchmark.launch dataset:. The program died after generating final optimized trajectory, and produced an error message like this:

================================================================================REQUIRED process [benchmark-1] has died!
