This is a bug report for perl from rich@richelberger.com,
generated with the help of perlbug 1.40 running under perl 5.20.2.
-----------------------------------------------------------------
[Please describe your issue here]
Please refer to RT 90452 for background and original symptom. #NYCHackathon
In regular shells, the path expression ‘foo/…’ should fail and return an empty list.
<code>
use strict; use warnings; use 5.10.00;
mkdir a;
my @result = lstat ‘a/…’;
say for @result;
</code>
In Linux / Mac, it results in an empty array since it is file not found.
On Windows, the result is:
$VAR1 = 0;
$VAR2 = 0;
$VAR3 = 16832;
$VAR4 = 0;
$VAR5 = 0;
$VAR6 = 0;
$VAR7 = 0;
$VAR8 = 0;
$VAR9 = 0;
$VAR10 = 0;
$VAR11 = 0;
$VAR12 = '';
$VAR13 = '';
