Hello,

Virgile already answers to your main issue. But...

This part of Frama-C is not related to your issue about building new 
expressions. What is called "Computation" in the Plug-in Development 
Guide is now called "State". That is a global value of a plug-in related 
to the AST (e.g. the result of your analysis stored in an hash table 
indexed by C statements). In order to be compliant with the Frama-C 
project system, you must use Hashtbl provided by State_builder instead 
of OCaml standard Hashtbl.

However,

I directly answer to this issue in the BTS 
(http://bts.frama-c.com/view.php?id=1036).

Hope this helps,
Julien
