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