Hi Yaakov,
the program compiled with -O0 is here
http://matzeri.altervista.org/x86_64/ncview/
you can also install with
setup-x86_64.exe -X -O -s http://matzeri.altervista.org
It requires: libnetcdf7 libpng16 libudunits0 libX11_6 libXaw7 libXt6
On http://matzeri.altervista.org/works/ncview/
you can find a small test database (~2Mb)
$ ncview s.nc
to run it.
I also loaded a picture of how to replicate the crash.
Until only the first rows of "Var" is selected everything is fine,
the data are presented in other windows, while with the second row
it usually crashes at the 3rd selection.
Regards
Marco
