[Boost-users] [Interprocess] Minimal size of a managed_shared_memory

Hello, A managed_shared_memory is a typedef for a basic_managed_shared_memory using rbtree_best_fit as allocation algorithm. In the documentation : http://www.boost.org/doc/libs/1_53_0/doc/html/interprocess/memory_algorithms... It is said at the and of the page : "In most 32 systems with 8 byte alignment the minimum size of a block is 24 byte". I am on Windows XP SP3 32 bits. The alignement is 8 byte. But if I create a managed_shared_memory with a size lesser than 120 bytes, my app crashes. This value comes from several get_min_size function, the deepest being in the rbtree_best_fit class. So I wonder which value we can grant to the documentation above. How are the 120 bytes used ?
