In this case one has to remember about ABE - application binary
compatibility. Each process has to be compiled with the same version of STL.
If processes are compiled with different version of STL, the object size
might be different, so for sure it is a bug.

You can't. An stl object is just a class object, which is storing it's
data in the heap of process. So if you just copy stl object into another
process, it will contain pointers to a data which is in the heap of
different process.
I think it may be possible. He just requires an allocator which works on
shared memory.
