[Frama-c-discuss] Strange results

To explain in a bit more detail what happens, let us write \U(e) the
join of the evaluation of e in all possible states for the chosen
statement.
What is displayed by the gui is
- \U( v ) is e is a syntactically constant variable v
- \U( t[ \U(i) ])  if e == t[i]
- \U( (* (\U(p))).a ) if p == p->a
etc. So when p is not constant, instead of seing \U(p -> a) as you
might want, you see the over-approximation above.

Hope this clarifies things,
