Hi All,

I wonder when the shared_ptr deleter is destroyed.

I have a shared_ptr with a custom deleter. I would expect when the last shared pointer to the object is gone then not only the deleter method will be called, but the deleter function object is also released. As I see the deleter is taken by value and stored by value in the reference counter, so I do not understand what is going on.

How is the deleter mean to be freed?

Thanks,
Tamas

struct MyClassDeleter
{
        ~MyClassDeleter()
        {
                // Break point is set here
        }

        void operator()(MyClass* item)
        {
                // Break point is set here
        }
}


{
        auto sharedPtr = boost::shared_ptr<MyClass>(new MyClass, MyClassDeleter)
}

// shared_ptr leaves the scope here, the custom deleter is called (parenthesis operator)
// the deleter instance is however not destroyed, the breakpoint in the destructor does not hit
