  =head1 NAME
  
  perlfreebsd - 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 FreeBSD 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 in versions 4.5 and earlier that can cause a SEGV when
  reading large directories. A patch for FreeBSD libc is available
  (see L<http://www.freebsd.org/cgi/query-pr.cgi?pr=misc/30631> )
  which has been integrated into FreeBSD 4.6.
  
  =head2 C<$^X> doesn't always contain a full path in FreeBSD
  
  perl sets C<$^X> where possible to a full path by asking the operating
  system. On FreeBSD the full path of the perl interpreter is found by using
  C<sysctl> with C<KERN_PROC_PATHNAME> if that is supported, else by reading
  the symlink F</proc/curproc/file>. FreeBSD 7 and earlier has a bug where
  either approach sometimes returns an incorrect value
  (see L<http://www.freebsd.org/cgi/query-pr.cgi?pr=35703> ).
  In these cases perl will fall back to the old behaviour of using C's
  C<argv[0]> value for C<$^X>.
