Source: golang-github-anacrolix-missinggo Followup-For: Bug #1021408 debci is not currently able to reproduce the error in a barrage of 10 repetitions, on both unstable and testing.
It's the nature of flakey tests to not reproduce well, but still I'd expect the failure to show in at least 1 in 10. Perhaps the problem was fixed elsewhere, e.g in glibc 2.34-3 patch git-atomic-compiler-builtins.diff (although there was one missinggo failure with libc6 2.34-3) I'll run a barrage of more tests and upgrade missinggo to a recent version. If armhf tests continue not to fail then I guess we can close this bug.
