Yeah it is a bug that is normally fixed from
r1997. If updating the code doesn't help, tell me! :P
Update svn and remake the library, don't forget to reinstall it:
~$ cd rtabmaplib
~/rtabmaplib$ svn up
~/rtabmaplib$ cd build
~/rtabmaplib/build$ make
~/rtabmaplib/build$ make install
~/rtabmaplib/build$ cd ~/catkin_ws
~/catkin_ws$ catkin_make
