What compiler are you using? This SWIG-generated code gives people lots of warnings, but it hasn't caused any errors yet. Also, which version of Python do you have on your machine?
I don't really like SWIG that much, and I have been considering rewriting the interpreter-embedding classes for Python and Perl manually instead. We would get clean code and no warnings.
Obviously that typecast is the problem, and I'll check in a fix. But if this requires a lot of fixing, then it would be more profitable to recode than to hack.
