I've tried it on the following, and I get the test failure on all of them.
- Mac OS X (El Capitan, 10.11.3) using a perlbrew perl (v5.22.1)
- Mac OS X (El Capitan, 10.11.3) system perl (v5.18.2)
- Ubuntu (precise, 12.04.5 LTS) using a perlbrew perl (v5.16.2)
- Ubuntu (precise, 12.04.5 LTS) system perl (v5.14.2)
Perhaps this is due to a difference in C libraries between windows and unix systems?
UPDATE: I forgot to mention that all of these are 64-bit.
