Initiating shutdown!

How can I solve this problem.

You need to give more details. This text just says it crashed because of a segfault. I have no idea what you are doing, how you built rgbdslam and its dependency, on what operating system (with version) and so on.

@fusionpdc did you solve it? because i have the same problem, i am using a virtual machine of ubuntu 16.04 and ros kinetic to make it work

Remember this is a very generic problem description. The OP may have a very different root cause than anyone else who gets a segfault.

If you report such a problem, please include more information.

A good way to do this is either

• enable core dumps, let rgbdslam_v2 crash, open the core dump in gdb and print a backtrace
• Launch rgbdslam_v2 in the debugger, by adding a launch-prefix in the launch file: launch-prefix="gdb -ex run --args". Then, let it crash and type bt when the gdb prompt appears, to obtain a backtrace.
