[Frama-c-discuss] New Frama-C version: Fluorine



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.

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.
