Core dump when running with Udacity's car simulator

[billow06]

Hello,
I followed the readme and compiled the code (ubuntu16.04 and required libraries are all installed). However, when I start the autonomous mode of the car simulator, the program breaks with logs as follows,

Listening to port 4567
Connected!!!
terminate called after throwing an instance of 'std::domain_error'
what(): type must be string, but is null
Aborted (core dumped)

I wonder it is due to some configuration problem. Since I do not take the nanodegree class, could you please help me with this issue. Thanks.
