I found more CPAN distributions with a similar fail pattern​:

  * ROAM/MooseX-Role-JSONObject-v0.1.0.tar.gz
  * CSSON/Dist-Zilla-Plugin-Stenciller-HtmlExamples-0.0201.tar.gz
  * CSSON/Dist-Zilla-Plugin-Stenciller-MojoliciousTests-0.0200.tar.gz
  * JSWARTZ/Poet-0.16.tar.gz

But all of these work again with v5.25.8-76-gb1b8fb6.
