 From Benjamin Root on the scipy-dev mailing list (June 14, 2010):
 I was trying out the scipy.io.netcdf module in order to work
 on the documentation and I came across a way to segfault out
 of python.  If you open an existing netcdf file as read-only
 and then try to set a scalar value using .assignValue for a
 1-element netcdf_variable, the program segfaults rather than
 raising an exception.

 Here is an example to go with a very small netcdf file as a test:

 from scipy.io import netcdf
 f = netcdf.netcdf_file("testdata.netcdf", 'r')
 tval = f.variables['t']
