rviz segfaults when node that publishes marker crashes (ros-pkg ticket #4463) #356

hershwg · 2012-09-19T22:10:38Z

I've got a simple node that publishes a marker to rviz. Whenever I kill the node with "ctrl-c", rviz segfaults and crashes. I'm sure I have a problem with my node, that I will fix, but it looks like rviz doesn't like it when a publisher hangs up on it.

My package "sticky_marker" is attached. To duplicate this failure,

"rosmake sticky_marker" and "rosrun sticky_marker sticky_marker".
Start rviz and add a marker to the display with the topic "erratic_pose_marker".
Press "ctrl-c" in the "sticky_marker" window

rviz output below:
{{{

[watts] I probably should've noted that I'm using stage as an erratic simulator.

[jfaust] If that's where it's crashing, that looks a lot like a driver bug. What's your nvidia driver version?

hershwg · 2012-09-19T22:10:43Z

[jfaust] oh... and following your instructions it works fine with the cturtle debs on my machine. I have a version of the 195.36.31 driver

hershwg · 2012-09-19T22:10:43Z

[watts] I'm using the nVidia developer drivers on both machines, version 260.24. That could explain this. Once nVidia releases a new version of their driver, I can test it with that to see if the problem goes away. I'm glad this works on the real drivers.

hershwg · 2012-09-19T22:10:44Z

[jfaust] Definitely a driver problem. See #4461

…tionFinder (ros-visualization#356) To fix the following warnings (converted to errors by compile options): error: destructor called on non-final 'MockProjectionFinder' that has virtual functions but non-virtual destructor [-Werror,-Wdelete-non-virtual-dtor] error: destructor called on non-final 'MockWindowManagerInterface' that has virtual functions but non-virtual destructor [-Werror,-Wdelete-non-virtual-dtor]
