found 917500 3.8.0+repack1-3 thanks Hi. Sorry for the reopening but this does not seem fixed.
I can still reproduce the error in our test machine (using sbuild) and it also fails (with a different error) in reproducible-builds: https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/liggghts.html (More to the point, my autobuilders normally have LC_ALL=C in the environment, so setting LC_ALL=C explicitly is unlikely to have any effect). Thanks.
