Hi all, Recently I changed my hardware from x86 to a Pandaboard (arm). But now I have problems to subscribe to a "const nav_msgs::Odometry::ConstPtr&" publisher. I allways receive a "bus error" (sigbus) subscribing to the topic.

Here ist the trac of the error:

Program received signal SIGBUS, Bus error. allInOne<ros::serialization::istream, geometry_msgs::point_<std::allocator<void="">

&> (m=..., stream=<synthetic pointer="">) at /opt/ros/fuerte/include/geometry_msgs/Point.h:208 208 stream.next(m.z); (gdb) quit

Can anyone confirm this problem or give me a hint to solve it?

Thanks Robin

This is a bug in the deserialization code in ROS, interacting badly with the arm hard-float support (armhf). I've had good success running ROS Electric and Groovy on Ubuntu Oneiric armel. (soft-float).

I suspect it will work with later versions of Ubuntu armel, but I haven't had time to try.

I have had the same issues. Armel seems to work very well, but when I moved to armhf, I got the bus error. I posted a similar issue at: http://answers.ros.org/question/52326/arm-architecture-with-armhf-port-move_base-bus-error-alignment-trapexception/

This has been fixed for quite a while now. You may want to try running your node in a debugger, and if that doesn't help, open a new question and include which version of the UDOO, which version of ROS you're using, and the code for the subscriber that is crashing.
