Hello, The initial (and only, AFAIK) problem with the given proposal was that the following code asserted: boost::monotonic::inline_storage<100*sizeof(int)> storage1; // create local storage on the stack boost::monotonic::vector<int> deathrow(storage1); // create a std::vector that uses this storage for(int i = 0; i < 100; ++i) deathrow.push_back(i); I offered to get back to the list when I had looked at it. I am doing so now. The `problem` is that std::vector allocates more than it needs, as you add to it. So while it may seem fine to allocate space for 100 ints, then make a monotonic::vector<int> and add 100 ints to it, it will fail to allocate the required excessively sized buffer. The `fix` in this case is to simply give it a larger buffer. This has no impact on the utility of the proposed librrary. Regards, Christian.
