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.
