I've got my _Sword.so module to compile and I statically linked libsword.a and libclucene.a into it. So far, I'm able to create the objects fine, but when I try to get my modules, Python crashes with the following trace:

I'm just playing around, reading the example C++ files and trying to translate that into python. Here's what I did to cause the error:

+-( ~/scratch ):> python

>>> mod = mods.begin()
>>> mod
<Sword.PySwigIterator; proxy of <Swig Object of type 'swig::PySwigIterator *' at 0x315db0> >
>>> mod.next()
Bus error

Same thing happens with I try and read anything from the iterator. It just crashes python.

Any ideas?

Thanks!
