Thanks for the report. It's seems to be related to a problem in alt-ergo with the record theory : the addition of the helper assertions trigger more fact on record comparisons. Without these helpers, alt-ergo give up very quickly (less than 1s), which can be a sign of incompleteness. Goals are proven with Z3, though. Regarding cvc3, it is indeed a why3 issue, if any. L.

I'm forced to insert the assertions HELPER and HELPER2 in order to discharge all POs, when in the Oxygen release I didn't need this kind of assertions. Without HELPER, BOUND cannot be proved and without HELPER2 the post condition cannot be proved. Note: the rest of the assertions were inserted to help me pinpoint the problem. > > http://pastebin.com/p5AdPN2n > > Also, in the previous release of frama-c there was a problem with cvc3 processes not being killed. This problem now happens more ofter but i'm guessing this is a problem related to why and not frama-c. > > Thanks! > _______________________________________________ > 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 -------------- next part -------------- An HTML attachment was scrubbed...
