Hello, we just fixed the implementation of getDeltaT (it was still sending integers via the socket instead of the intended doubles). However, that should not have been causing the crash by itself. Nevertheless, can you check with the latest development version if the problem still occurs? If so, please send the traci script for reproducing the crash along with the necessary inputs.
