Hello. I just experienced a very weird core dump from Terminator and Octave practically at the same time.
I had several Terminator windows open, one of which contained an Octave session (but it wasn't running any script at the time). Other active programs were: qutebrowser (a few open windows) and a Python interpreter (also not running anything at the time). The system is up to date, though I have not restarted since last update (which occurred 10 hours ago) because there were no kernel updates.
The crash happened when I was working on a Vim file. All my Terminator windows were abruptely closed, along with all their child processes (PDF files, several Vim documents, Python interpreter, Octave session and some other programs). My qutebrowser session passed intact because I hadn't started it from any Terminator process.
Anyone can shed a light on this intriguing mystery? Please let me know if any more info is needed.
