[ncl-talk] Sub: Regrid error..

[Laura Fowler]

Hi Dale:

I encountered the same kind of segmentation fault when using ncl/6.4.0
compiled with the intel compiler. I addressed this issue to ncl-talk
on October 25th. Note that my settings were different and I was not
using Opt at DstRegional = True.

Mary Haley suggested to use ncl/6.4.0 compiled with the gnu compiler.
Changing compilers solved the issue I had with the "segmentation
fault". I am forwarding you her reply separately. You may be
encountering the same issue too. Hope this helps.

Cheers,
Laura
