| =item * |
| |
| L<B::Deparse> has been upgraded from version 1.03 to 1.04, to address two |
| regressions in Perl 5.14.0: |
| |
| Deparsing of the C<glob> operator and its diamond (C<< <> >>) form now |
| works again. [perl #90898] |
| |
| The presence of subroutines named C<::::> or C<::::::> no longer causes |
| B::Deparse to hang. |
| |
| =item * |
| |
| L<Pod::Perldoc> has been upgraded from version 3.15_03 to 3.15_04. |
| |
| It corrects the search paths on VMS. [perl #90640] |

| =head1 Internal Changes |
| |
| =over |
| |
| =item * |
| |
| The compiled representation of formats is now stored via the mg_ptr of |
| their PERL_MAGIC_fm. Previously it was stored in the string buffer, |
| beyond SvLEN(), the regular end of the string. SvCOMPILED() and |
| SvCOMPILED_{on,off}() now exist solely for compatibility for XS code. |
| The first is always 0, the other two now no-ops. |
| |
| =back |
| |
| =head1 Bug Fixes |
| |
| =over 4 |
| |
| =item * |
| |
| A bug has been fixed that would cause a "Use of freed value in iteration" |
| error if the next two hash elements that would be iterated over are |
| deleted. [perl #85026] |
| |
| =item * |
| |
| Passing the same constant subroutine to both C<index> and C<formline> no |
| longer causes one or the other to fail. [perl #89218] |
| |
| =item * |
| |
| 5.14.0 introduced some memory leaks in regular expression character |
| classes such as C<[\w\s]>, which have now been fixed. |
| |
| =item * |
| |
| An edge case in regular expression matching could potentially loop. |
| This happened only under C</i> in bracketed character classes that have |
| characters with multi-character folds, and the target string to match |
| against includes the first portion of the fold, followed by another |
| character that has a multi-character fold that begins with the remaining |
| portion of the fold, plus some more. |
| |
| "s\N{U+DF}" =~ /[\x{DF}foo]/i |
| |
| is one such case. C<\xDF> folds to C<"ss">. |
| |
| =item * |
| |
| Several Unicode case-folding bugs have been fixed. |
| |
| =item * |
| |
| The new (in 5.14.0) regular expression modifier C</a> when repeated like |
| C</aa> forbids the characters outside the ASCII range that match |
| characters inside that range from matching under C</i>. This did not |
| work under some circumstances, all involving alternation, such as: |
| |
| "\N{KELVIN SIGN}" =~ /k|foo/iaa; |
| |
| succeeded inappropriately. This is now fixed. |
| |
| =item * |
| |
| Fixed a case where it was possible that a freed buffer may have been read |
| from when parsing a here document. |

| =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 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. |
