[ncl-talk] segmentation default when reading variables

Mon Dec 11 00:49:49 MST 2017

Hi Dennis,

I just uploaded the file:
name: EDIII_BIC_1990.nc

uname -a:
Darwin Noelias-MBP.fritz.box 15.5.0 Darwin Kernel Version 15.5.0: Tue Apr
19 18:36:36 PDT 2016; root:xnu-3248.50.21~8/RELEASE_X86_64 x86_64

gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr
--with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 7.3.0 (clang-703.0.31)
Target: x86_64-apple-darwin15.5.0
Thread model: posix
InstalledDir:

Please let me know if the file was totally uploaded (I think it was 100%
uploaded before the connection was closed).

Thanks again,

Noelia
