[Frama-c-discuss] Assigns broken for arrays?

Although loop assigns is accepted by the ACSL parser, it is not
supported by the jessie plugin yet (you should have a warning about
that on stderr), so that it doesn't help to prove the assigns.
When loop assigns will be supported by the jessie plugin (maybe in the
Next Version, but don't take that as a formal statement), the current
version of your specification should be proved without much trouble.

Sorry if this situation wasn't clear from my previous e-mail.

Best regards,
