Hi Natalya,

This seem to be a deficiency in the current interface that we should fix asap.

As an immediate workaround, which could be faster then what Junxiao suggested, but not future-safe code:

    auto pitIterator = pit.begin();
    // ...
    shared_ptr<pit::Entry> pitEntry = pitIterator.operator->();
