[ncl-talk] Segmentation fault with image size(frame size)

[Kihang Youn]

Hi All,

I got some segmentation errors during draw or frame steps.

To debug or figure out a workaround, I tried commenting out the functions.

First, once I comment on the gsn_add_polyline function, Seg error does not occur.

But polyline is needed, so I uncommented it and looked at the other values, and as a result, no error occurred by adjusting the following variables res at vpYF or res at tmYLLabelDeltaF.

Can such variables affect the size of an image or frame and cause a segmentation fault?

For information, the ncl script draws multiple pictures with the do statement, but an error occurs only in some pictures.

Please let me know if you have any suggestions.
