[Boost-users] boost vector including non standard objects

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<Listener*,
managed_shared_memory::segment_manager> ShmemAllocator;
typedef boost::interprocess::vector<Listener*, ShmemAllocator> 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
