Hi Leonhard, Thank you for investigating this. It looks like it's sumocfg specific: If I run your example against my own compiled sumo which is known to crash then your main.cpp works. If I run one of our sumocfg files with your main.cpp then I get the readIsSafe error.
I will investigate further the differences between our scenarios and yours. It may be the way we're defining our traffic. Do you think it could be because of the following warning which we now get? Warning: Defining car following parameters in a nested element is deprecated in vType 'CarA', use attributes instead!
