Hi!

If I run the demo and try to use geane with the kalman filter I get the following error. Somehow a 0 momentum is appearing. It appears to me to be inside CbmGeanePro, since in geaneTrackRep the values look alright. I am not sure where the bug is.

Could anyone try to reproduce this, please!

  *** S/R ERPROP   IERR =    2


     *** Error in subr. TRPROP   2  called bysubr. ERPROP



Program received signal SIGFPE, Arithmetic exception.
