It has nothing to do with rviz, or even using OpenGL, just being linked against it.  For example, this exhibits the same crash:


roscd roscpp_tutorials
LD_PRELOAD=libGL.so bin/listener


roscd roscpp_tutorials
bin/talker

I think I've been having this problem too, and I'm glad to hear that
upgrading drivers seems to solve it. But I'm also still puzzled how
killing another process causes rviz to crash simply because it uses
opengl. I would have thought that the graphics and topic subscription
parts of rviz would be fairly independent. What is it about the other
process crashing, whose only connection (AFAIK) with rviz is through a
ROS topic, that triggers the bug in the nvidia driver?

Cheers,
Pat
