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. + +=head1 AUTHOR + +Steve Peters <steve@fisharerojo.org> + +Please report any errors, updates, or suggestions to F<perlbug@perl.org>. + |
