2020-04-29 06:06:22 -0500 | marked best answer | Random segfaults for python rqt plugin I've tried to write a couple of rqt plugins in order to make interaction with our ROS system easier. I'm not confident or familiar with QT (or C++) from beforehand, so I wrote the plugins with basis in the rqt-plugin tutorials. One of the plugins is a used for controlling a simulation. This interacts with a node controlling a simulated clock using a service, and echoes the simulated clock to a QLineEdit. The plugin works well, but randomly exits with segfault. This seems to happen more often when my system has been running for a while. If I restart the plugin after it segfaults, it may segfault straight away, or run for an extended time period. After a restart, the plugin runs for a long time before I experience problems. Some thought on what may cause this, without being able to fix it:
I've run the plugin both by launching I'm running Meldic Morenia on ubuntu 18.04 with kernel 5.3.0-45-generic. All inputs or suggestions are highly appreciated! The plugin code: (more) |
