John, are your changes just to CBC or also to CGL? <br><br>I was using CBC 2.3.0 and CGL 0.54.0. I tried switching to CBC 2.3 but I get the same error.<br><br><br><br><div class="gmail_quote"><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

<br>
I have modified code in 2.3 and trunk. Does it fix problem?<br>
<br>
John<br>
