note full ci results - RHEL-8, AlmaLinxu 8, OpenSUSE-15 (but not 16), SLES and Windows have a bison version older than 3.6.3(?) when this was introduced. The reproducibility this adds is when its built in the same environment in different paths? Can you elaborate why its important and to what degree this improves the reproducibility? |
