Python doesn't have any call-by-reference support at all [1], so I'm  
not surprised that a straight translation of the call-by-reference C  
function doesn't work.

Unfortunately I don't know enough about SWIG to suggest a work- 
around.  Hopefully someone more versed in SWIG will have a bright  
idea.  If you don't find anything in the Python space, you might try  
poking around in Java references, since Java has the same call  
semantics as Python.

Best wishes,
