Ubuntu autopkgtest of the latest github.com/xtaci/smux v1.3.4 (Debian package golang-github-xtaci-smux/1.3.4+ds-1) fails Ubuntu autopkgtest on ppc64el:
(Special thanks to @LocutusOfBorg for telling me about this issue over IRC on #ubuntu-devel as this apparent test regression is preventing golang-github-xtaci-smux's migration to Eoan, i.e. Ubuntu 19.10.)
Further tests reveal that:
- It is not limited to ppc64le (ppc64el); I was able to reproduce the same errors on my amd64 computer.
- It is found in both v1.1.0 and v1.3.4 (master as of this writing)
- It happens randomly, and I need to run loops like below to trigger the errors:
