Benchmarks generated by the Rust verifier Verus (https://verus-lang.github.io/verus/guide/) on the project Verus Systems (https://dl.acm.org/doi/10.1145/3694715.3695952) and processed using Mariposa (https://github.com/secure-foundations/mariposa). z3 solves this without nonlinear, but it cannot be expressed in SMTLib without a nonlinear theory.
This benchmarks was originally run with z3 with the following options:
    (set-option :auto_config false)
    (set-option :smt.mbqi false)
    (set-option :smt.case_split 3)
    (set-option :smt.qi.eager_threshold 100.0)
    (set-option :smt.delay_units true)
    (set-option :smt.arith.solver 2)
    (set-option :smt.arith.nl false)
    (set-option :pi.enabled false)
    (set-option :rewriter.sort_disjunctions false)
    (set-option :smt.arith.solver 6)
