Re^2: Latest Strawberries: addresses reported by "p", Devel::Peek, etc.

Thanks for explanation. Looks like "'COW + p' leak by design now" to me, but maybe the case is too artificial for real life. I think pack has "You are responsible..." warning already.

use strict;
use Devel::Peek;
$Devel::Peek::pv_limit = 3;     # useless for UTF8
use warnings;
use feature 'say';

say $^V;

sub mem { say qx( tasklist /nh /fi "PID eq $$" ) =~ m[(\S+ K)$] }
mem();
{
    my $r = \ join '', 'a' .. 'z'; 
    $$r x= 1e7; 
    my $s = $$r;
    my $p = pack 'p', $s;
}
mem();
{
    my $r = \ join '', 'a' .. 'z'; 
    $$r x= 1e7; 
    my $s = $$r;
    my $p = pack 'p', $s;
}
mem();
