6533	Can't use map with incomplete type and interprocess allocator	Erik Jensen <Erik.Jensen@…>	Ion Gaztañaga	"A boost::container::map using boost::interprocess::allocator cannot be instantiated with an incomplete value type, even though the allocator itself can be.

Sample code:
{{{
#include <string>
#include <boost/interprocess/allocators/allocator.hpp>
#include <boost/interprocess/containers/map.hpp>
#include <boost/interprocess/managed_shared_memory.hpp>

class Incomplete;
typedef boost::interprocess::allocator<std::pair<std::string, Incomplete>,
    boost::interprocess::managed_shared_memory::segment_manager> Allocator;
typedef boost::interprocess::map<std::string, Incomplete,
    std::less<std::string>, Allocator> IncompleteMap;
class Incomplete
{
    Allocator foo;      // No error here
    IncompleteMap bar;  // Error!
};
}}}
The error occurs as part of the instantiation of boost::container::container_detail::is_convertible by boost::container::container_detail::impl::extract_version. Using using boost::is_convertible instead fixes the problem on Visual Studio 20103"	Bugs	closed	To Be Determined	container	Boost 1.48.0	Problem	fixed
