Re: [sumo-user] Segmentation Fault SUMO 1.16 on Ubuntu
|
As is often the case with bugs in parallel code, you need a bit of load in critical sections to make it manifest. It's related to vehicles with rerouting device that change their route while they drive and then delete their old route with deletion triggered from multiple threads.
Thanks. I will test the nightly build tomorrow. But for your
information, I did test parallel routing in a simpler example using
OSM WebWizard and it worked fine. What didn't work was
device.vehroute.probability, but that has nothing to do with the
error.

I do not think I've changed something in my PYTHON app code when upgrading. Strange it breaks in both cases for you.
