Hi, we heavily use polygons to visualize data within sumo. During the development of the visualization we run into an error which terminated sumo with an error message similar to: "pure virtual function called".
The reason was a error in one of our calculations for the shapes used as polygons. The position of the shapes was filled with NaNs which we provided to sumo via TraCI. I didn't locate the code where the error ultimately arises, but i guess it has something to do with the used RTree which sorts the polygons by their positions. Since relational operators for NaNs always fails, i guess that this cause the error somehow. Due to the error message i suspected an memory handling error within sumo. I wasted a lot of time before i noticed the NaNs. Therefore as an enhancement i would suggest to add NaN checks in the implementation of TraCI. A proper error message would prevent other developers to run into the same issues. What do you think about it? Shall i create a issue on github?
