<p dir="auto">I've recently been having trouble with the voxl-dfs-server. I'm running voxl-suite 1.0 on Sentinel. I've recalibrated the stereo cameras and enabled the server, but it isn't running. When I try to run I get a "stack smashing" error. Has anyone else encountered this issue? Any recommendations to fix? Code is below, all inputs are appreciated!</p>
