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
