Dennis,
while looking at gsn_csm_vector, please take look at memory issues,
Yesterday
I reported problems that arose between versions 6.1.2 and 6.3.0, and have
been traced to gsn_csm_vector or gsn_csm_streamline. The code and the
data file are rather lengthy, I uploaded these two files onto
ftp.cgd.ucar.edu as lech.lobocki at is.pw.edu.pl
In brief:
- the whole script executes with no problems by NCL 6.1.2
- It fails reporting "Segmentation fault" when executed
by 6.3.0 (tried on two machines, a 4GB PC with Fedora 23
and a 32GB server with CentOS 7 - both with a binary
ncl package form fedora/centos repositories.
- commenting out lines #252 and 254 - where gsn_csm_streamline is called
allows the script to pass.
