Hello
I'm running 18.04 with the latest updates. I've been getting occasional segfault crashes that I've only really ever noticed while running flightgear. I'm not sure though if the problem is with flightgear, ubuntu, or a hardware issue? Recently I've started starting flightgear with gdb and here is the output
Code:
Thread 1 "fgfs" received signal SIGSEGV, Segmentation fault.
