    <p>Hi Xinjie,</p>
    <p>Thanks for your data. I could reproduce your error and it seems
      it is linked to the Joseph projector. In particular, there is a
      hard-coded tolerance factor used to compute the planes which are
      crossed by the lines. Decreasing that factor seems to remove the
      crash in my tests. <br>
    </p>
    <p>So a quick fix may be to reduce that threshold (you can replace
      the <i>src/projector/iProjectorJoseph.cc</i> file by the one in
      attached, then recompile castor).</p>
    <p>I am not sure yet whether the crash is limited to that factor.
      Let me know if it fixes the error for you.<br>
    </p>
    <p>Best,<br>
      Thibaut<br>
