Introduced by
|
|
L<perl #113536|https://rt.perl.org/Public/Bug/Display.html?id=113536>, a memory
|
|
leak on every call to C<system> and backticks (C< `` >), on most Win32 Perls
|
|
starting from 5.18.0 has been fixed. The memory leak only occurred if you
|
|
enabled pseudo-fork in your build of Win32 Perl, and were running that build on
|
|
Server 2003 R2 or newer OS. The leak does not appear on WinXP SP3.

Copy the values used to perturb hash iteration when cloning an

The list above is almost certainly incomplete as it is automatically generated
|
|
from version control history. In particular, it does not include the names of
|
|
the (very much appreciated) contributors who reported issues to the Perl bug
|
|
tracker.
|
|
|
|
Many of the changes included in this version originated in the CPAN modules
|
|
included in Perl's core. We're grateful to the entire CPAN community for
|
|
helping Perl to flourish.

=head1 Reporting Bugs
|
|
|
|
If you find what you think is a bug, you might check the articles recently
|
|
posted to the comp.lang.perl.misc newsgroup and the perl bug database at
|
|
http://rt.perl.org/perlbug/ . There may also be information at
|
|
http://www.perl.org/ , the Perl Home Page.
|
|
|
|
If you believe you have an unreported bug, please run the L<perlbug> program
|
|
included with your release. Be sure to trim your bug down to a tiny but
|
|
sufficient test case. Your bug report, along with the output of C<perl -V>,
|
|
will be sent off to perlbug@perl.org to be analysed by the Perl porting team.
|
|
|
|
If the bug you are reporting has security implications, which make it
|
|
inappropriate to send to a publicly archived mailing list, then please send it
|
|
to perl5-security-report@perl.org. This points to a closed subscription
|
|
unarchived mailing list, which includes all the core committers, who will be
|
|
able to help assess the impact of issues, figure out a resolution, and help
|
|
co-ordinate the release of patches to mitigate or fix the problem across all
|
|
platforms on which Perl is supported. Please only use this address for
|
|
security issues in the Perl core, not for modules independently distributed on
|
|
CPAN.
