Segmentation fault when measuring something in ROS

[TheCynosure]

Describe your issue here and explain how to reproduce it.

Your environment

• OS Version: Ubuntu 18.04
• ROS Distro: Melodic
• RViz:

I am displaying a large pointcloud that is constantly moving (A slam implementation). I am then going and trying to measure the distance between two points and this is causing a segmentation fault. Specifically I click the measure tool, then click on the map is when the program crashes.
Here is the stacktrace that I collected from GDB:

[rhaschke]

I cannot reproduce this issue. Could you please provide a minimal example robustly showcasing this segfault? For example, provide a small program to publish a moving point cloud or provide a rosbag file of your point cloud topic.
Does the segfault occur on/after? the first or the second click?

[TheCynosure]

Let me see if I am able to publish the bag file on here.

[rhaschke]

Because you closed this issue, I guess you were not able to reproduce the issue?

[TheCynosure]

I have been able to zoom in very close to large pointclouds and try and take measurements causing crashing many times but I can't seem to reproduce it / come up with a scenario where it always keeps occuring.
