I have installed and built rgbdslam v2 with ROS Kinetic on Unbuntu 16.04 64-bit . I am trying to run rgbdslam_v2 the first time. It crashed with SIGSEGV in g2o::OptimizationAlgorithmLevenberg::computeLambdaInit(). I ran it again in gdb and got the following message.

(gdb) run Starting program: /home/cchien/ws/devel/lib/rgbdslam/rgbdslam [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

I would appreciate any help and suggestion for fixing the problem. Thanks, C. Chien
