Hi Christoph,

I'm unsure of what you mean exactly: with Frama-C Lithium and why 2.17,
there is a proof obligation related to the post-condition
swapped{...}(...), and it is proved by alt-ergo, Z3 and Simplify. In
fact, there are 5 PO, one for each ensures clause and assigns clause of
the specification (+ 3 more for safety, but this is not related to your
function contract). What is the PO that you expected to find in Why's
output and which is not there?

Best regards,
