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

Your problem was that the EXE was using the single-threaded runtime, but the
DLL has been set to multithreaded. The mutex lock in the DLL was spinning
forever.

When I set both to multi-threaded, it works, even with different heaps.

Interesting issue. It can be made to work even in this case but this will
cost performance.
