You rock. There are more cases where data ought to be cleaned up, but I forget now. Let me look at some old custom converter code this weekend before I come up with more tests. > I think the registration issue is not hard to fix. But is the "crash" > mentioned in BPL manual still valid? We still can't produce any crash. The only way I can think of for this to happen is if boost.python holds some reference to an object held by the python interpreter before PyFinalize was called. The only candidate I could find is the fundamental PyTypeObject used by boost.python but nothing popped out on a cursory look, but then I doubt anyone can find bugs in Dave's code upon cursory examination :-) I am not sure that I can spend enough time on this prior to the end of your GSOC period.
