[pkg-go] Bug#850198: golang-github-dvsekhvalnov-jose2go: FTBFS randomly (failing tests)

[Santiago Vila]

Package: src:golang-github-dvsekhvalnov-jose2go
Version: 1.2-1
Severity: important

Dear maintainer:

I tried to build this package in stretch with "dpkg-buildpackage -A"
(which is what the "Arch: all" autobuilder would do to build it)
but it failed:

--------------------------------------------------------------------------------

This is just how the build ends, not necessarily the relevant part.

I've put several build logs here:

https://people.debian.org/~sanvila/golang-github-dvsekhvalnov-jose2go/

If this is really a bug in one of the build-depends, please use reassign and affects,
so that this is still visible in the page for this package.

The bug should be reproducible with sbuild on a single CPU virtual machine,
provided you try enough times (as the failure happens randomly).

After building 200 times, the failure rate observed here is about 6%.

Thanks.
