Just to confirm, I'm using "perl 5, version 24, subversion 2 (v5.24.2) built for MSWin32-x64-multi-thread"

The code at the error in Utils.pm is

use constant is_perl55 => ($] < 5.005_50);
use constant is_perl56 => ($] < 5.007 && $] > 5.005_50);
use constant is_sane_perl => $] > 5.007;

I have browsed the lib files but I don't see where "strict subs" is set. Also, my code was working as of 11/24/17.

The output from the code you provided is:
