Please do not hesitate to fill in a bug report, or feature wish.

Initially, you wanted to hide some local side effect from the "public" 
contract of your function. This is a need I completely understand. 
Unfortunately checking this is a very difficult theoretical question, 
because of all the potential sharing/aliasing of data structures. ACSL 
does not offer such a feature in its current state.
