------------------------------------------+--------------------------
 My code below is a very simple example, that should work to communicate
 between x86 and x64. But it doesn't...

 If I create it in x64 and open in win32, the win32 process stuck at a lock
 at
 function ''try_based_lock'' in
 `boost/int/sync/detail/common_algorithms.hpp`

 In the other way around: win32 create, x64 open: the x64 process crashes
 at
 ''name_length'' in `segment_manager_helper.hpp` while trying to find the
 name from an index (''priv_generic_find'' in `segment_manager.hxx`).

 {{{#!c++
 #include <iostream>
 #include <boost/interprocess/managed_shared_memory.hpp>

 int main() {
     namespace bip = boost::interprocess;
     // open in WIN32, create in x64
 #ifdef _WIN32
     bip::managed_shared_memory msm(bip::open_only, "TestIPC");
 #elsif X64
     bip::shared_memory_object::remove("TestIPC");
     bip::managed_shared_memory msm(bip::create_only, "TestIPC", 4096);
     msm.construct<uint32_t>("Data")[1](10);
 #endif
     // Get Data and print it
     auto data = msm.find<uint32_t>("Data");
     if (data.second == 1) {
         std::cout << *data.first << std::endl;
     }
     std::cin.ignore();
     return 0;
 }
 }}}

 I am using Windows 7 and VC12.
