|
|---|
| 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
|
|---|
| 17 | in preference to non-re-entrant versions. There is an incompatability in
|
|---|
| 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.
