Hello everyone,

the following trivial example highlights a memory leak according to MSVC 
2010. Does anybody know why this is and how it can be avoided?

     // The following three directives are required for MSVC's automatic 
memory
     // leak detection.
     #define _CRTDBG_MAP_ALLOC
     #include <stdlib.h>
     #include <crtdbg.h>

     #include <boost/interprocess/managed_shared_memory.hpp>

     int main(int argc, char *argv[])
     {
         {
             using namespace boost::interprocess;
             static const char* shMemIdentifier = "MySharedMemory";
             struct ShMemCleaner {
                 ShMemCleaner() { 
shared_memory_object::remove(shMemIdentifier); }
                 ~ShMemCleaner() 
{shared_memory_object::remove(shMemIdentifier); }
             } cleaner;

             // Create a new segment with given name and size
             managed_shared_memory segment(create_only, shMemIdentifier, 
1024);

             int* intInShMem = segment.construct<int>("myInt")(2);
             segment.destroy<int>("myInt");
         }
         _CrtDumpMemoryLeaks();
     }

Thank you very much!

Best,
Michael
