            Bug ID: 1011333
           Summary: PerlIO::via leaks a foreign memory
           Product: Fedora
           Version: 18
         Component: perl
          Assignee: jplesnik at redhat.com

This simple test:


#!/usr/bin/perl
use strict;
use warnings;
#use utf8;

{
  package PerlIO::via::Bug;

  sub PUSHED {
    return bless {}, $_[0];
  }
  sub READ {
    return $_[2];
  }
}

open my $fh, '<:raw:via(Bug)', '/dev/null' or die "Cannot open, $! $?";
read $fh, ( my $buf ), 1024;
print $buf;


accesses foreign data (and puts them into $buf and prints them). All perls are
affected, the specific output depends on perl version and on the "use utf8"
pragma. Valgrinds warns on write(2) with uninitialized memory.

Reported to upstream as
<https://rt.perl.org/rt3//Public/Bug/Display.html?id=119961>.

All Fedoras are affected.
