I've been seeing quite a few test failures in Sqitch, where the tests just exit with no output after a certain number of tests. Here's an example:
http://www.cpantesters.org/cpan/report/100e46c0-b2f1-11e4-b986-627b8971dd2f
This happens most often on Perl 5.10, but I have seen it happen on 5.12, too, like here:
https://travis-ci.org/theory/sqitch/jobs/50537629
I have not been able to replicate it myself, but asked Andreas about the above cpan-testers failure and he replied with:

I asked Andreas what version was installed. His reply:
