Dear maintainers,

With a recent upload of golang-github-chmduquesne-rollinghash the
autopkgtest of syncthing fails in testing when that autopkgtest is run
with the binary packages of golang-github-chmduquesne-rollinghash from
unstable. It passes when run with only packages from testing. In tabular
form:
                       pass            fail
golang-github-chmduquesne-rollinghash        from testing    4.0.0-1
syncthing              from testing    0.14.52+ds1-2
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is contributing to the delay of the migration
of golang-github-chmduquesne-rollinghash to testing [1]. Due to the
nature of this issue, I filed this bug report against both packages. Can
you please investigate the situation and reassign the bug to the right
package? If needed, please change the bug's severity.
