Subject: [boost] shared_ptr/intrusive_ptr conflict

Hi,
Following snippet fails to compile with gcc 4:
----------------
#include <boost/shared_ptr.hpp>
#include <boost/intrusive_ptr.hpp>
boost::shared_ptr<void> sharedPtr;
template <class T>
boost::shared_ptr<T>
get_concrete()
{
return boost::static_pointer_cast<T,void>(sharedPtr);
}
int main()
{
boost::shared_ptr<int> p = get_concrete<int>();
}
----------------
due to the presence of intrusive_ptr.hpp. it seems like SFINAE should have
kicked in.
Any help with how to work this around? Do we need to fix above header?
Gennadiy.
