I am trying to fix issues I know about + look around for similar cases. This issue happened because CurAddressState was accessed before processing sections commands,
where it is assigned initially. At this moment I do not know about other similar cases which can trigger null pointer access to CurAddressState. 
Though it is probably can be possible, do you know any ?

I think we can go step by step probably and see if we need some generic helper or something if see another cases with CurAddressState.
