If you are using a fixed address shared memory, you should specify the 
mapping address, otherwise, you can get a different one each execution. 
After all, this is what fixed mapping is about ;-) I think I should 
force the use of an address in this class (currently 
fixed_managed_shared_memory segment is a typedef of 
basic_managed_shared_memory segment so by default and an address is not 
requested).

Please, try the same specifying an address (add another parameter to the 
constructor). The address depends on the OS you are using. Try, for 
example (void*)0x30000000. Or just use managed_shared_memory segment. 
Why do you need fixed address mappings?
