I've exposed a C++ class to Python using Boost Python. The class, let's say it's called Entity, contains private static data, which is an array of strings. Though I think it implements it using MFC's CPtrArray.
I've also exposed a public function from Entity - let's say it's called foo. This function accesses the private static data (the string array). I have multiple instances of Entity stored in a custom C++ container, which is also exposed to Python as class EntityList. In Python, I retrive an Entity from the EntityList: elist = EntityList() elist.append(Entity()) elist.append(Entity()) entity = elist.get_at(0) entity.foo() But it crashes inside foo() as the private static data is empty; or rather the string array is empty. I know before that point that the private static data is valid when accessed earlier by the C++ code as the program works fine. It just won't work from Python, so somehow the private static data has been blown away but I can't work out where or why. The static data is setup at initialisation - my Python code is only called long after initialisation is complete. I added a static dump() function to the Entity class that dumps the string array, and even if I just do the following in Python: Entity.dump() in Python, the private static data is empty. Doing the same from C++ works fine. Weird. I know this is an impossible question to ask, but can anyone think of something obvious I need to look into?
