| 7 | README.openbsd - Perl version 5 on OpenBSD systems | |
| 8 | ||
| 9 | =head1 DESCRIPTION | |
| 10 | ||
| 11 | This document describes various features of OpenBSD that will affect how Perl | |
| 12 | version 5 (hereafter just Perl) is compiled and/or runs. | |
| 13 | ||
| 14 | =head2 OpenBSD core dumps from getprotobyname_r and getservbyname_r with ithreads | |
| 15 | ||
| 16 | When Perl is configured to use ithreads, it will use re-entrant library calls | |
| f858446f | 17 | in preference to non-re-entrant versions. There is an incompatibility in |
| 23e2b7a9 SP |
18 | OpenBSD's C<getprotobyname_r> and C<getservbyname_r> function in versions 3.7 |
| 19 | and later that will cause a SEGV when called without doing a C<bzero> on | |
| 20 | their return structs prior to calling these functions. Current Perl's | |
| 21 | should handle this problem correctly. Older threaded Perls (5.8.6 or earlier) | |
| 22 | will run into this problem. If you want to run a threaded Perl on OpenBSD | |
| 23 | 3.7 or higher, you will need to upgrade to at least Perl 5.8.7. | |
