* preserve the initial state of the solver with push/pop for multiple objectives Signed-off-by: Lev Nachmanson <levnach@hotmail.com> * Fix memory corruption in Z3_polynomial_subresultants The API function had a memory corruption bug where allocating the result vector while the default_expr2polynomial converter was still in scope could corrupt the converter's internal expr2var mapping. Fixed by restructuring the code to: 1. Complete all polynomial computation in a scoped block 2. Store results in a temporary expr_ref_vector 3. Let the converter go out of scope 4. Then allocate and populate the result vector Also improved the test to: - Use randomized testing with 20 iterations - Test both cases: variable in polynomials and variable not in polynomials - Use proper reference counting (inc_ref before dec_ref) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> --------- Signed-off-by: Lev Nachmanson <levnach@hotmail.com> Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com> |
