Various header files embed the timestamp when it was generated in comments: https://tests.reproducible-builds.org/debian/rb-pkg/bookworm/amd64/diffoscope-results/snacc.html /usr/include/snacc/c/asn-useful.h ·*····This·.h·file·was·generated·by·snacc·on·Fri·May·19·17:42:30·2023 vs. ·*····This·.h·file·was·generated·by·snacc·on·Sun·Apr·17·13:25:08·2022 The attached patch fixes this by removing the timestamps from the code that generates the header files. With this patch applied, snacc should become reproducible on tests.reproducible-builds.org! live well, vagrant
