[ncl-talk] Segmentation fault using addfiles

[David Brown]

Hi Andrew,

The fact that the "statistical_process_duration" is 0 suggests that
NCL is getting confused by these files in some way. Can you make your
files available? I would like to be able to run your script to see
what is going on. Possibly it is something that is already fixed in
the development version, but I will need to take a look.

Instructions for uploading are on the Support->Report Bugs page that
you can get to from the NCL web site. Be sure to let me know (offline)
the names of all the files. Thanks.
