Greetings! Firstly, this is not a regression, the behaviour was present in 1.30, too. I have attached a simple program that should demonstrate the behaviour, but the core is these lines, with foo being derived from enable_shared_from_this:
// 1 std::auto_ptr<foo> g(new foo); boost::shared_ptr<foo> f(g); // 2 std::auto_ptr<foo> g(new foo); boost::shared_ptr<foo const> f(g); // 3 std::auto_ptr<foo const> g(new foo); boost::shared_ptr<foo const> f(g);
In all three cases, I'd expect to be able to call shared_from_this(). However, only the first two cases really work.
I've now modified the CVS version of shared_ptr to handle these cases. With the modifications in place, your example now prints: plain foo failed const failed shared_ptr<foo> works const works shared_ptr<foo const> const works shared_ptr<foo> from auto_ptr<foo> works const works shared_ptr<foo const> from auto_ptr<foo> const works shared_ptr<foo const> from auto_ptr<foo const> const works Thank you for the suggestion. :-)
