[Frama-c-discuss] Nested loops

Sure, but I **did** remove the last assertion in the file, and the results are those I give in my answer (with the assertion, there are 13 proof obligations, not 12).
Although, I’m using the development version of Frama-C, which is 21.1+dev, and you are probably using 21.1 ; must be investigated further…
