<br>
I encountered the same kind of segmentation fault when using ncl/6.4.0<br>
compiled with the intel compiler. I addressed this issue to ncl-talk<br>
on October 25th. Note that my settings were different and I was not<br>
using Opt@DstRegional = True.<br>
<br>
Mary Haley suggested to use ncl/6.4.0 compiled with the gnu compiler.<br>
Changing compilers solved the issue I had with the "segmentation<br>
fault". I am forwarding you her reply separately. You may be<br>
encountering the same issue too. Hope this helps.<br>
<br>
Cheers,<br>
Laura<br>
