Getting segmentation faults with Intel Realsense Cameras

Follow
Kevin Chow

I keep getting segmentation faults with the realsense cameras (I use 2 D415 cameras at once). This segmentation fault has appeared on the realsense-viewer on a freshly installed OS (Ubuntu 18.04) and freshly installed libraries installed via the instructions here (https://github.com/IntelRealSense/librealsense/blob/master/doc/distribution_linux.md). 

When I try to access the 2nd camera I have attached, it will often segmentation fault. Also it segmentation faults when it turn on and then turn off streams on any of the cameras.

I do not have this problem on another system I have which have not updated for some time. Is this an issue with the latest update to librealsense?

    Hi Kevin Chow  The segmentation faults in the RealSense Viewer that you are experiencing are likely not related to how recent the SDK version is.

    Do you have segmentation faults when only one camera is attached to the computer, please?

    Hi MartyG, I get them with both 1 camera is attached or 2. It happens when I simply turn on a stream (depth or colour) and then turn said stream off via the realsense-viewer.

    My current system conditions are:

    OS: Ubuntu 18.04.5

    Cameras: D415 with firmware version 5.12.10.00

    Realsense-viewer: v2.41.0

    My most common situations for seg faults arising is:

    (1) When I go to view my second camera and select it, the entire realsense-viewer freezes and then segmentation faults.

    (2) When I turn on the depth stream and then the colour stream and then move to turn 1 of those streams of (any)

    The most reliable way to trigger this segmentation fault is with 2 cameras, if you turn on all camera streams and then turn off any of the streams. The realsense-viewer freezes up and then crashes with a segmentation fault.

    I will continue this case at the GitHub version that you posted so that we are not communicating in two places at the same time.  Thanks!
