still working on 2445, root cause remains elusive although it should be crackable. Other (and smaller) examples are welcome. For example, I could make a crude delta-debug of 2445 by decomposing some of the top level connectives. Maybe Mathias and Aina's delta debugging tools apply, but I haven't operated them myself.
@NikolajBjorner Z3 now reports unsat
on this correctly!
Depends on random seed
This is most likely another incarnation of https://github.com/Z3Prover/z3/issues/2445
But it's hard to tell it's exactly the same root-cause, so reporting it anew.
For the following benchmark; z3 reports
sat
with value ofs1 = 2275
. The benchmark is actuallyunsat
. If you indeed put(assert (= s1 2275))
into the benchmark (see the commented out section about 15 lines from the top) z3 reportsunsat
.
