1 | If you read this file _as_is_, just ignore the funny characters you |
2 | see. It is written in the POD format (see pod/perlpod.pod) which is | |

6 | ||
7 | README.freebsd - Perl version 5 on FreeBSD systems | |
8 | ||
9 | =head1 DESCRIPTION | |
10 | ||
11 | This document describes various features of FreeBSD that will affect how Perl | |
12 | version 5 (hereafter just Perl) is compiled and/or runs. | |
13 | ||
14 | =head2 core dumps from readdir_r with ithreads | |
15 | ||
16 | When perl is configured to use ithreads, it will use re-entrant library calls | |
17 | in preference to non-re-entrant versions. There is a bug in FreeBSD's | |
18 | C<readdir_r> function that can cause a SEGV when reading large directories. | |
19 | A patch is available | |
20 | (see http://www.freebsd.org/cgi/query-pr.cgi?pr=misc/30631 ) | |
21 | and will hopefully be integrated into FreeBSD 4.6. | |
22 | ||
23 | =head2 $^X doesn't always contain a full path | |
24 | ||
25 | perl 5.8.0 sets C<$^X> where possible to a full path by asking the operating | |
26 | system. On FreeBSD the full path of the perl interpreter is found by reading | |
27 | the symlink F</proc/curproc/file>. There is a bug on FreeBSD, where the | |
28 | result of reading this symlink is can be wrong in certain circumstances | |
29 | (see http://www.freebsd.org/cgi/query-pr.cgi?pr=35703 ). | |
30 | In these cases perl will fall back to the old behaviour of using C's | |
31 | argv[0] value for C<$^X>. | |
