+=head1 NAME
+
+README.openbsd - Perl version 5 on OpenBSD systems
+
+=head1 DESCRIPTION
+
+This document describes various features of OpenBSD that will affect how Perl
+version 5 (hereafter just Perl) is compiled and/or runs.
+
+=head2 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 incompatability in
+OpenBSD's C<getprotobyname_r> and C<getservbyname_r> function in versions 3.7
+and later that will cause a SEGV when called without doing a C<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.
