[Bug 1011333] New: PerlIO::via leaks a foreign memory
https://bugzilla.redhat.com/show_bug.cgi?id=1011333
Bug ID: 1011333
Summary: PerlIO::via leaks a foreign memory
Product: Fedora
Version: 18
Component: perl
Assignee: jplesnik(a)redhat.com
Reporter: ppisar(a)redhat.com
QA Contact: extras-qa(a)fedoraproject.org

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.
