[Frama-c-discuss] Jessie: Timeout for Simplify broken?

Hello Jens and Virgile,

I also noticed that Jessie generates VCs for arithmetic safety even if
there are no arithmetic operations apart from comparisons. Eg, for enums
val1, val2,

if(val1 != val2)

generates 4 VCs and


generates 2 VCs. I don't see how a arithmetic overflow might occur here.
What does Jessie try to prover here?
