  Thank you for your reply.
  I modify my codes as you said and everything goes well without seg-fault.Thank you very much,but when I run my programme with beamOn,the old problem comes,It says:

  ---> Begin Of Event: 1
  G4MagIntegratorDriver::OneGoodStep: Stepsize underflow in Stepper
  Step's start x=9.10312 and end x= 9.10312 are equal !!
  Due to step-size= 8.85047e-20 . Note that input step was 0.885047

  and it stops without any messages.I try to change my input electric values,but that problem still exits.what is the possible reason of it?Can you give me some suggestion?Thank you for your time!
