9=head1 DESCRIPTION
10
11This document describes various features of OpenBSD that will affect how Perl
12version 5 (hereafter just Perl) is compiled and/or runs.
13
14=head2 OpenBSD core dumps from getprotobyname_r and getservbyname_r with ithreads
15
16When Perl is configured to use ithreads, it will use re-entrant library calls
17in preference to non-re-entrant versions. There is an incompatibility in
18OpenBSD's C<getprotobyname_r> and C<getservbyname_r> function in versions 3.7
19and later that will cause a SEGV when called without doing a C<bzero> on
20their return structs prior to calling these functions. Current Perl's
21should handle this problem correctly. Older threaded Perls (5.8.6 or earlier)
22will run into this problem. If you want to run a threaded Perl on OpenBSD
233.7 or higher, you will need to upgrade to at least Perl 5.8.7.
