The general shmem shared memory allocator was never intended to be used 
with STL containers, because I don't know about any STL implementation 
that accepts allocators that define allocator::pointer types as non-raw 
pointers. The only possibility was using fixed address mapping.

You can use "fixed_managed_shared_memory" instead of 
"managed_shared_memory" (it's in the reference but there is no example 
in the code) to achieve this. allocators created from the segment 
manager produced by "fixed_managed_shared_memory" create shared memory 
allocators compatible with STL implementations. Hope this helps.
