A função Puppet Split falha

Question

Problema

A função split do Puppet falha desde que o Puppet foi atualizado para a versão 3.5.1 , enquanto isso funcionou até 3.4.3

Código

 1  $ports_regex = "80\|443"
 2
 3  $ports_string       = regsubst($ports_regex, '\\|', ',', 'G')
 4
 5  notify{"CP1 ${ports_string}":}
 6
 7  $ports_array = split($ports_string, ',')
 8
 9  notify{"CP2 ${ports_array}":}
10
11  each($ports_array) |$port| {
12      notify{"CP3 ${port}":}
13
14      file {"${port}":
15          path => "c:/temp/puppettest/${port}",
16          ensure => present;
17      }
18  }

Resultado

3.4.3
