Description :
It is not possible to access the members of the base class through a pointer to the derived class. (pointer to object of derived struct -> member of base struct)
The problem only occurs if these two conditions are fullfilled:
- The member is inherited from the base class.
- The access happens inside an acsl clause. (i.e. after a requires or an ensures)
There are examples for all cases in the attached file "problem308.cpp".
