Hi, It seems that, actually, many proof obligations are missing. The simple invariant over variable i is easily discharged on simple goals, but the proof obligation for preservation is missing in your case. There is a dangling node in the internal CFG generated by WP for your code, but don't know why ! Somebody else reported a simiar problem recently, but I can not figure out what is the origin. As reported by Dillon, rephrasing the code can help. We are investigating the problem ! L.
