perlfreebsd - Perl version 5 on FreeBSD systems DESCRIPTION
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 "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 http://www.freebsd.org/cgi/query-pr.cgi?pr=misc/30631 ) which has been integrated into FreeBSD 4.6. $^X doesn't always contain a full path in FreeBSD perl sets $^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 "sysctl" with "KERN_PROC_PATHNAME" 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 argv[0] value for $^X. AUTHOR
