WebbThere are some valid uses cases for sharer_ptr in a single threaded program but they are rare. Some people use shared_ptr as a replacement for a number of different things, from pass-by-const-ref to simple composition or to unique_pointer, littering the code with shared_ptrs. It then becomes hard to reason about lifetimes. Webbget_pointer_safety; get_temporary_buffer; C++11. make_shared; return_temporary_buffer
