| Subject: | Date::Manip Memory Leak |

Hi CPAN,
Can you please raise the following critical bug.
Would you please look at the following issue whereby UnixDate leaks memory
on RHEL 6 64-bit. Tested with version 6.31 of Date::Manip. The memory leak
can be observed quite easily by comparing the output of the pmap utility
over different periods (example below) against the following script.
Appreciate your efforts in the open source community!
########Script Start (test.pl)
#!/usr/bin/perl -w
use strict;
use Date::Manip qw(UnixDate);
my $date;
for (my $i=0;; $i++)
{
for (my $j=0; $j<100; $j++)
{
$date = UnixDate(localtime, '%C');
}
sleep 1;
}
########Script End
[root@myhost ~]# rpm -qa | grep release
redhat-release-server-6Server-6.2.0.3.el6.x86_64
[root@myhost ~]# ps -ef | grep test.pl | grep -v grep
root 779 29753 3 14:56 pts/3 00:00:00 /usr/bin/perl -w ./test.pl
[root@myhost ~]# pmap 779 > /tmp/test.pmap; sleep 10; pmap 779
