Hi, Is shared_array completely thread-safe. including destruction/reference counting? http://www.boost.org/doc/libs/1_33_1/libs/smart_ptr/shared_ptr.htm#ThreadSaf... // thread A p3 = p2; // reads p2, writes p3 // thread B // p2 goes out of scope: undefined, the destructor is considered a "write access" /bb/source/boost/boost_1_33_1/boost/detail/sp_counted_base_pt.hpp
