Thank you for the quick answer. It does work if I call it from a single non-main thread. But everything must be called from that thread, including the import of the module. I still do not understand what is the problem. The C++ code is not thread safe, but I call it from 1 Python thread at a time. Anyway, I have always called it from multiple Python threads without any problem. Having put a few printf in the module, I can say that it crashes exactly when it tries to create C threads.
