Hi Nicolai, thanks for following up on this.
I am in the process of determining what causes the crash. I fear that to reproduce the problem you will need to have ROS installed, I have not yet been able to reproduce it without ROS running. I do not want to inflict the installation of ROS on you without being 100% sure. I am using Roassal because this is for Live Robot Programming (http://pleiad.cl/LRP <http://pleiad.cl/LRP>) which uses a dynamic visualization of the running code. To reproduce the bug (until now) I need to develop code in LRP when using ROS, and then it happens randomly. I realize that this is too much to ask for an outsider to reproduce the bug (I did not expect anybody to download and install PhaROS to try to reproduce, thanks for that!!). Can you inform me how I can get you more useful debug info to you? I will keep trying to find minimal steps to reproduce in the mean time. > 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).
