Quick guess: a binary incompatibility, e.g. how you compile your extension vs how the libboost_python you link against was built.
Your code looks good to me. I'd try different compile and link options for building your extension. Alternatively, you could use cmake, e.g. this worked for me a few months ago: https://github.com/rwgk/stuff/tree/master/test_with_boost_python cmake is pretty good at figuring out matching compile and link options. (You could just look at what it does and then adopt the same options elsewhere.)
