There is an incompatibility in 20OpenBSD's C<getprotobyname_r> and C<getservbyname_r> function in versions 3.7 21and later that will cause a SEGV when called without doing a C<bzero> on 22their return structs prior to calling these functions. Current Perl's 23should handle this problem correctly. Older threaded Perls (5.8.6 or earlier) 24will run into this problem. If you want to run a threaded Perl on OpenBSD 253.7 or higher, you will need to upgrade to at least Perl 5.8.7. 26 27=head1 AUTHOR 28 29Steve Peters <steve@fisharerojo.org> 30 31Please report any errors, updates, or suggestions to 32L<https://github.com/Perl/perl5/issues>. 33 34
