That's very exciting to hear, I have been hoping for better smart pointer
support in the analyzer. I have a code snippet which you are welcome to
adapt if it helps you:
I wrote this after asking for help on this mailing list a few months ago.
This was not for checking null dereferences, but it does some simple
modeling of std::unique_ptr, so it may end up being useful to you. I should
warn you that I am a relative beginner at the static analyzer, so it may
not even be correct, maybe your mentors will even use it as an example of
what not to do :-)
I wish you a great experience in your internship.
