[Frama-c-discuss] Behavior specification with ghost variables



Thank you for the explanation. When I use the Pre label in the final 
assertion of my example, these cannot be proven either.

I have reformulated the behavior specifications into two equivalent 
ensures clauses as you have suggested, these can then be proved.

However, I very much like bhavior specifications because they nicely
match informal specifications and they can be labelled for reference
in the documentation. Is there any other way apart from ghost
variables to achieve my goal with behaviors?
