We just added support for overloaded new operator for most compilers. That might be an option. The wrapper binary_option might be what you want. The of course there is the save/load construct data. Robert Ramey Matthias Troyer wrote:

Hi, i am planning to use the boost serialization library to implement checkpointing for an ASP/Sat solver. Unfortunately, the solver implements one (very special) optimization that makes use of a zero-sized array at the end of a class. I have found no way to store something like this using the library. There is a small program in the attachment that contains data structures similar to the ones used in the solver code. This would need a mechanism to control the allocation of memory during deserialization. Do you see any possibility do serialize something like this?
Regards and thanks, Roland
Uhhhh .... that is dangerous code. and this object is neither Assignable nor Copyable. Do you really need to make use of that optimization? In essence you need to control the memory allocation:
Base *x = new(new unsigned char[sizeof(Derived) + 42 * sizeof(int)]) Derived(42);
and have the serialization library do such a new operation instead of the default one. Robert, is there a hook for that?
