Only on Perl 5.10, a bizarre error occurs like https://travis-ci.org/yak1ex/String-Unescape/jobs/24323913
It is reproduced in my local environment (Cygwin) by the following procedure.
- Clone https://github.com/yak1ex/String-Unescape
- Install newly Perl-5.10.1 environment by perlbrew
- Install Dist::Zilla like
perlbrew exec --with perl-5.10.1 cpanm Dist::Zilla
- Install dependent modules like
dzil authordeps | perlbrew exec --with perl-5.10.1 cpanm
perlbrew exec --with perl-5.10.1 perl /usr/local/bin/dzil build
causes error shown in output.log
