The other provers return a time-out. > I have the same behavior as Pascal (no proof for Equal(s,t) and 0==1 in equal_pop) for alt-ergo 0.91, Simplify 1.5.4 and Z3 2.0 (Frama-C Boron and Why 2.26). Just in case, when you ran your experiment with equal_pop, you had the ensures 0==1 commented out in the spec of pop itself, as it is in the archive, right? Otherwise, the issue lies there.
