i'm excited to present you a technique which i occasionally invented shared pointers are very good helpers they help us to manage dynamically allocated memory however it seems so natural i have never seen so far that one be allowed to delete shared pointer like this:
shared_ptr<int> p = new int, q = p; delete p; assert(!p); //neither assertion fires assert(q);
Am I missing something?
cat shared.cpp #include <boost/shared_ptr.hpp>
int main( ) { boost::shared_ptr<int> p = new int, q = p; delete p; assert(!p); //neither assertion fires assert(q); }
