testing fcl collision library (https://github.com/flexible-collision-library/fcl)
parallel collision calling on fcl objects.
This test just makes two fcl objects and calls the 'collide' function in separate threads
which results in a race condition. A similar problem exists for ContinuousCollide. Also, this issue can't be solved by making copy of fcl objects when doing parallel computation. Same error occurs.
