No, the best we can hope for is a crash when it is running from debugger, you can start the vm with a debugger or attach the debugger to a running process. If we are lucky, the debugger will show a stacktrace. > > On Oct 24, 2015, at 19:45, Nicolai Hess <nicolaih...@gmail.com> wrote: > > Can you provide the image file. > What exactly runs in the image (does it depend on ROS or > does it crash even without it).
