I am trying to spawn pr2 urdf xacro model in gazebo along with its controllers using pr2_controller_manager. I am facing segmentation fault at :-
Thread 28 "gzserver" received signal SIGSEGV, Segmentation fault. [Switching to Thread 0x7fff63ffd700 (LWP 17825)] 0x00007fffc96ac0ed in ros::NodeHandle::destruct() () from /opt/ros/kinetic/lib/libroscpp.so
And it's backtrace is
