Would using register_ptr_to_python explicitly and consistently instead of the online shared_ptr declaration potentially eliminate some side-effects? I cannot yet isolate why my real app crashes in python when it tries to do an eval into one of my wrappers.
Overall, I doubt it. Usually putting shared_ptr in the class_ template params would allow you to do more fancy shared_ptr tricks, not less. And as I said before, it might be necessary if you use enable_shared_from_this.
What your previous example showed, though, was that it might be useful to use register_ptr_to_python on every type you ever make a shared_ptr to in C++ *in addition* to putting shared_ptr in the class_ templates - you'll get some warnings in Python about redundant converters, and those will tell you which of those extra declarations it's safe to remove. Any that remain might help fix your problem.
