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.
