Bad cast

[TylerPaquette]

Hi,

I am using v0.5 on Ubuntu 22, built and installed from source. I am running this through matlab and all is well but I am getting a segfault following the quickstart example. The only error I can see is this in terminal, and it seems to happen on calling optimal_laptime function.

[C++ exception] -> std::bad_cast
terminate called after throwing an instance of 'std::exception'
  what():  std::exception
Aborted (core dumped)

The whole program I am running is just this (quickstart code):

import sys,os,inspect
sys.path.append("/home/tyler/fastest-lap/src/main/python/")
import fastest_lap

vehicle_name = "car"
fastest_lap.create_vehicle_from_xml(vehicle_name, "/home/tyler/fastest-lap/database/vehicles/f1/mercedes-2020-catalunya.xml");
track_name = "catalunya"
fastest_lap.create_track_from_xml(track_name, "/home/tyler/fastest-lap/database/tracks/catalunya/catalunya_adapted.xml");
s = fastest_lap.track_download_data(track_name,"arclength");

options  = "<options>"
options += "<output_variables>"
options += "<prefix>run/</prefix>"
options += "</output_variables>"
options += "<print_level> 5 </print_level>"
options += "</options>"

#print(vehicle)
#print(track)
#print(s)
#print(options)

run = fastest_lap.download_variables(*fastest_lap.optimal_laptime(vehicle_name, track_name, s, options));

Should note this terminal output is from simply running this using python (3.10) and not the matlab api.

Have you seen this or know what might cause this?
Thanks
