found 850507 4.20.0-2 thanks Hello Jordi.
As you have already noticed, this still fails in (most of the) reproducible builds autobuilers: https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/golang-github-tideland-golib.html To double-check, I've built this a lot of times in my own autobuilders. The result: Tried 200 times. Failed 98 times. I've put all (both failed and successful) my build logs here for you to see: https://people.debian.org/~sanvila/build-logs/golang-github-tideland-golib/ Note 1: It did never fail in two of my autobuilders, leaseweb1 and leaseweb2. Those happens to be the slowest machines I have currently (all the others are faster). Maybe this means something. Note 2: If it becomes non-trivial to fix the tests "the right way" I would suggest that they are just temporarily disabled for stretch. Thanks.
