Rviz version 1.14.23: librviz related crash after ubuntu (20.04) update

[arbephoenix]

We are using ROS Noetic on Ubuntu 20.04 and have an application (GUI) that we developped and uses librviz.so
All was working well for the last two year until the latest Ubuntu update broke our application.

The Rviz version after the ubuntu update is 1.14.23

Below is the segmentation fault we are seeing.
Any hints why we started seeing this after the latest ubuntu update?

[rhaschke]

Could you please try the latest version 1.14.25, building from source or from the ROS testing repo?

[rhaschke]

Unfortunately, there was a bug introduced, which was not noticed during the testing phase.

[arbephoenix]

Thank you for confirming!
Do you have any estimation of when 1.14.25 is going to hit the next Ubuntu update.

We will try building from sources to confirm the fix

Thanks again for you prompt response!

[rhaschke]

Usually, sync intervals are within 1-2 months. Until then, I suggest to install the debian package from the ROS testing repo.

[arbephoenix]

Thank you!
I updated ros-noetic-rviz from ros-testing to 1.14.25 using the suggested method and the issue is resolved.

Have a great weekend,
