NAME

       perlopenbsd - Perl version 5 on OpenBSD systems

DESCRIPTION

       This document describes various features of OpenBSD that will affect how Perl version 5 (hereafter just Perl) is compiled and/or runs.

   OpenBSD core dumps from getprotobyname_r and getservbyname_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 an
       incompatibility in OpenBSD's "getprotobyname_r" and "getservbyname_r" function in versions 3.7 and later that will cause a SEGV when called
       without doing a "bzero" on their return structs prior to calling these functions.  Current Perl's should handle this problem correctly.
       Older threaded Perls (5.8.6 or earlier) will run into this problem.  If you want to run a threaded Perl on OpenBSD 3.7 or higher, you will
       need to upgrade to at least Perl 5.8.7.

NAME

       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.
