perlfreebsd - Perl version 5 on FreeBSD systems
This document describes various features of FreeBSD that will affect how Perl version 5 (hereafter just Perl) is compiled and/or runs.
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
function in versions 4.5 and earlier that can cause a SEGV when
reading large directories. A patch for FreeBSD libc is available
(see http://www.freebsd.org/cgi/query-pr.cgi?pr=misc/30631 )
which has been integrated into FreeBSD 4.6.
doesn't always contain a full path in FreeBSD
where possible to a full path by asking the operating
system. On FreeBSD the full path of the perl interpreter is found by using
if that is supported, else by reading
the symlink /proc/curproc/file. FreeBSD 7 and earlier has a bug where
either approach sometimes returns an incorrect value
(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
