| Subject: | segfaults if loaded twice |
It seems that signatures loaded twice with some core-stuff-modify module
(like Class::Accessor::Fast or Template) segfaults or gets into infinite
loop if Moose is loaded after it:
Segfaults:
use strict;
use warnings;
use signatures;
use signatures;
use Class::Accessor::Fast;
Goes into infinite:
use strict;
use warnings;
use signatures;
use signatures;
use Moose;
signatures.pm 0.06
Moose 1.08
Class::Accessor::Fast 0.33
Template 2.22
