Hi, This is the same situation as your example with a struct. The workaround is to introduce a ghost variable. There is no need to introduce ghost variables when you have two or more array assignments because Jessie does a special treatment of parallel assignments. However, the current discussion make me think that every assignments should be treated as parallel assignments are treated. I may consider adding this in the next release. - Claude On 10/21/2013 02:03 PM, Luciana Burgareli wrote: > Hi, > > This is a very simple example, but it was not proved. > > If we slightly modify the code and we add an assignment to the Ang2[1] > (and the related assigns and ensures clauses), both the ensures clauses > are proved. > > Why is not the attached example proved? > > How to solve this problem? > > We are using the Jessie Plugin, Why3 Verification Platform 0.81, > Fluorine-20130601 and the provers Alt-Ergo 0.95.2, CVC3 2.4.1, Gappa > 1.0.0 and Z3 4.3.2. > > > Luciana > > > > _______________________________________________ > Frama-c-discuss mailing list > Frama-c-discuss at lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/frama-c-discuss >
