[ncl-talk] Segmentation fault with addfiles and addfile

[Dennis Shea]

Hi Andrea,

The file is a 'run-of-the-mill' CAM5 file with 64-bit offset.

*%>* ncdump -k spcesm_cam5_control.cam.h0.1910-05.nc
64-bit offset
====================================================
Using *NCL 6.3.0* and *NCL 6.5.0* I tested addfile and addfiles using the
attached script


Try the attached.
