Re: [Boost-Users] MS VS 6: passing boost::shared_ptr<T> to a dll function

I don't know about MS, but in Borland a common source of DLL interface 
problems is
not using a common (shared) memory manager.

You might also check up on byte alignment.(4,8,16, or32 ?)

Other possibilities arise from other argument passed, which might be 
structs with >different<
definitions in the main and dll modules, e.g., std::ostream in 
multithread and non-multithread modes.
