Comment (by Yochai Timmer):

 The folder name is different, and in the older versions the file name was
 decorated by boost.

 Create 2 projects, a DLL and an executable. Link one project to boost 1.54
 or older (i used 1.51), and the other to boost 1.55.

 Then use the exact same code (different classes for a different name, the
 fact that you cant use the same shared memory object is another issue).


 {{{
 //in Dll1
 struct Test1
 {

 static void OpenSharedMemory() { boost::interprocess::message_queue
 sh(boost::interprocess::open_or_create, "Test1", 20,24); }

 }

 //in The executable
 struct Test2
 {

 static void OpenSharedMemory() { boost::interprocess::message_queue
 sh(boost::interprocess::open_or_create, "Test2", 20,24); }

 }
 }}}



 Now call them in the main function, the second call will always fail (you
 can change the order).


 {{{
 int main(int argc, char* argv[])
 {

 Test1::OpenSharedMemory();
 Test2::OpenSharedMemory();
 return 0;
 }
 }}}
