401=head1 Reporting Bugs
402
403If you find what you think is a bug, you might check the articles
404recently posted to the comp.lang.perl.misc newsgroup and the perl
405bug database at http://rt.perl.org/perlbug/ . There may also be
406information at http://www.perl.org/ , the Perl Home Page.
407
408If you believe you have an unreported bug, please run the B<perlbug>
409program included with your release. Be sure to trim your bug down
410to a tiny but sufficient test case. Your bug report, along with the
411output of C<perl -V>, will be sent off to perlbug@perl.org to be
412analysed by the Perl porting team.
413
414If the bug you are reporting has security implications, which make it
415inappropriate to send to a publicly archived mailing list, then please send
416it to perl5-security-report@perl.org. This points to a closed subscription
417unarchived mailing list, which includes all the core committers, who be able
418to help assess the impact of issues, figure out a resolution, and help
419co-ordinate the release of patches to mitigate or fix the problem across all
420platforms on which Perl is supported. Please only use this address for
421security issues in the Perl core, not for modules independently
422distributed on CPAN.
