There may also be +information at http://www.perl.org/ , the Perl Home Page. +.PP +If you believe you have an unreported bug, please run the 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 \f(CW\*(C`perl \-V\*(C'\fR, will be sent off to perlbug@perl.org to be +analysed by the Perl porting team. +.PP +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 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.
