     Type:  Bugs              |      Status:  new         
Milestone:  To Be Determined  |   Component:  interprocess
  Version:  Boost 1.49.0      |    Severity:  Problem     
 Keywords:                    |  
------------------------------+---------------------------------------------
 There is a very simple example:

 {{{
 #!cpp
 #include <iostream>

 #include <boost/interprocess/managed_windows_shared_memory.hpp>

 #include <boost/interprocess/smart_ptr/unique_ptr.hpp>
 #include <boost/interprocess/allocators/allocator.hpp>
 #include <boost/interprocess/containers/list.hpp>
 #include <boost/interprocess/sync/named_mutex.hpp>
 #include <boost/interprocess/sync/named_condition.hpp>
 #include <boost/interprocess/sync/scoped_lock.hpp>

 struct Request
 {
  int a;
 };

 template<typename Segment, typename T>
 class Channel
 {
 public:

  /// Value pointer in queue.
  typedef typename boost::interprocess::managed_unique_ptr<T,
 Segment>::type
   ValuePtr;

 };

 int main(int argc, char* argv[])
 {
  Channel<boost::interprocess::managed_windows_shared_memory,
 Request>::ValuePtr v;

  std::cout << "Test" << std::endl;

  return 0;
 }

 }}}

 I got this error in Visual Studio 2008:

 This example works fine in boost 1.48.0
