       perlopenbsd - Perl version 5 on OpenBSD systems


       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.
