The following two lines crash the kernel in 9.5 but not 9.4: xx = vector(GF(2), []) xx * xx It works correctly (with answer 0) over other finite fields or over QQ. Installation is Sagemath 9.5 in Ubuntu running under WSL for Windows; tested also in CoCalc Sagemath 9.5 (where it crashes) and CoCalc Sagemath 9.4 (where it correctly produces 0).
