Hello! I would like to create a vector in shared memory which includes objects of a class Listener*. Listener* was created by my own and is therefore no standard. When I try the following, using the boost interprocess library: typedef boost::interprocess::allocator ShmemAllocator; typedef boost::interprocess::vector MyVector; MyVector *ListenerVector; managed_shared_memory segment(create_only, "MySharedMemory", 65536); const ShmemAllocator alloc_inst(segment.get_segment_manager()); ListenerVector = segment.construct<MyVector>("ListenerVector")(alloc_inst); ListenerVector->push_back((Listener*)listener); The code works perfectly when I use a vector with integers, but it crashes when I use a vector with objects of my own class. I wanted to ask if it is possible to create a boost vector holding a non standard object and if so what I do wrong. Thank you very much for your help! Best regards, Sabine
