Fwd: [boost.interprocess] Are there pitfalls using managed_shared_memory?

Are there common pitfalls when using
boost::interprocess::managed_shared_memory in order to share a
variable in the following way (Cpp,Windows OS)?

managed_shared_memory managed_shm(open_or_create, "my_shm", 1024);
// Write
int *i = managed_shm.construct<int>("Integer")(42);
// Read
std::pair<int*, std::size_t> p = managed_shm.find<int>("Integer");

- Is the shared memory deleted, when the application is stopped?
- Do other programs or services can bear with this method without crashing?
-is there a danger that shared memory could be accumulated with some
kind of overflow?

Question: what does one have to consider when using this method?

Thanks for help.
