[Boost-users] Using shared_ptr across shared library boundary

Is there any problem with using shared_ptr and passing an instance of it to
a function in another shared library, such as a DLL under Windows ? Does the
reference count get updated correctly when the copy is passed to a DLL
function, so that when the last shared_ptr in either the original module or
the DLL goers out of scope, the actual pointer is correctly deleted ?

If this is not the case, that shared_ptr works correctly across DLL
boundaries in the manner described, does instantiating and exporting
shared_ptr template instances from the DLL to the module using the DLL solve
the problem ?
