No, I trust you when you say that the patch as the whole fixes the problem.
However, given the definition of get_type_deref I don't understand how it does
that. You patch has four hunks, and in two of the you check for pointer type 
and call get_target_type immediately after call to get_type_deref. It looks like it should
have no effect, so I'd like to understand what I'm missing.
