You are correct.  The proof goes through with the file attached to the message.  But the proof fails if the assertion “\at(dst, Pre) == \at(dst, Here)” at the end is deleted.  The question was just why that assertion is needed for the proof to go through.  Thanks!  -Mark

PS: Tomas Härdin asked about giving the solvers more time.  Increasing the time to –wp-timeout 600 had no effect.  My experience is that either the prover comes back quickly or it doesn’t come back, but I could use some guidance on how much time to give the provers.

I don’t really understand the problem. Without any assertion, I get instant proof for all loop invariants:
