Interprocess communication between x86 and x64 issue

[lutztonineubert@…]

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).

#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.
